GAINESVILLE, Fla. -- No. 23 Florida likely will be without quarterback Luke Del Rio against Southeastern Conference rival and 15th-ranked Tennessee next week.Del Rio injured his left knee in a 32-0 victory against North Texas on Saturday night, a huge setback for the Gators and their championship hopes.It doesnt look great, so well do whatever, said coach Jim McElwain, adding that former Purdue starter Austin Appleby would be the next guy up. Somebody else will play and well get some guys ready and move forward and get ready to go play next week.The injury overshadowed a dominant performance by Floridas defense, which allowed a school-record 53 yards on 50 plays. The previous mark was 59 yards allowed against Western Carolina in 2006.Defensive lineman Joshua Wheeler hit Del Rio low at the end of incomplete pass late in the third quarter, drawing a personal-foul penalty. Trainers and coach Jim McElwain rushed to the field as Del Rio ripped off his helmet. Del Rio eventually got up and walked to the locker room without any assistance.But that was hardly the end of it for Florida (3-0). McElwain, who clearly believed Wheelers hit was dirty, started yelling at the North Texas (1-2) sideline and had to be restrained by officials and then his players.When you see something like that, its my responsibility when their parents arent here to be their parents, McElwain said. I care about these kids. Theyre mine. I see something like that, it aint right.Both teams responded to McElwains tirade by stepping onto the field and moving toward the hash marks.He was trying to make a play and didnt mean to do it, North Texas coach Seth Littrell said. We are not trying to take cheap shots here.On the next play, Florida guard Martez Ivey was ejected for grabbing linebacker Fred Scott by the facemask during a run. Ivey will not be suspended for the first half of next weeks game against the Volunteers.It got a little gritty after that went down, Florida left tackle David Sharpe said.Del Rio completed 14 of 25 passes for 186 yards, with an interception.THE TAKEAWAYNorth Texas: Littrell, a former offensive assistant at Arizona, Indiana and North Carolina, is trying to change the culture at North Texas. Playing the Gators tough early -- the score was 19-0 through three quarters -- was a good start and something to build on in Littrells first season.Florida: The tune-up games are over. While handling UMass, Kentucky and North Texas, Floridas defense was dominant and its offense remains a work in progress -- especially without Del Rio. It remains to be seen how the Gators young and inexperienced offensive line will fare against the meat of the schedule.APPLEBYS TIMEAppleby started 11 games the last two years for the Boilermakers, leaving Purdue after 19 touchdowns and 19 interceptions. As a graduate transfer, he was eligible to play right away. You dont ever want to be somebodys caddie, Appleby said. You want the ball in your hands.McElwain said freshmen Kyle Trask and Feleipe Franks also may have to get ready to play.FOURTH-DOWN FAILURESFlorida could have scored more but got stopped on fourth-and-2 plays inside the 10-yard line. Mark Thompson was stuffed for no gain from the 5 in the first quarter, and Del Rio threw incomplete from the 8 in the second. The Gators are now 0 for 3 on fourth-down tries inside the 10 this season.NO CALLAWAYFlorida played without sophomore receiver Antonio Callaway, who missed the game because of bruised quadriceps. Callaway entered the game leading the Gators with 13 catches for 201 yards and two touchdowns. He is expected to play against Tennessee. The Gators got senior receiver Chris Thompson back, and he proved to be another deep threat. Thompson was suspended the first two games.POLL IMPLICATIONSFlorida should remain at or near No. 23 , making next weeks game at Tennessee the second in eight years in which both rivals were ranked. They also were both ranked in 2012. The Gators, who have won 11 in a row in the series, and Volunteers were both unranked the previous two meetings.UP NEXTNorth Texas: Opens Conference USA play at Rice (0-3). The Mean Green are 2-4 all-time against the Owls.Florida: Plays the Volunteers (3-0) for the 27th consecutive year. Florida is 20-6 during that stretch, including 11 straight wins that mark the longest streak since the programs first played in 1916.---AP college football website: www.collegefootball.ap.orgCheap Authentic Retro Air Jordans For Sale . -- If this was Aaron Gordons final home game at Arizona, and it almost certainly was, then he went out in style.

CARMEL, Ind. -- Crunching the FedEx Cup numbers has never been Jordan Spieths thing. Well, its not really anyones thing, as the various permutations can cause a headache.But Spieth is versed enough in the subject to know that a good day on Sunday can vault him into the top 5 in the FedEx Cup standings heading to the Tour Championship in Atlanta.And from that position, a win in the season-ending event means an overall FedEx Cup title.Spieth, who is tied for ninth and 10 shots back of tournament leader Dustin Johnson through three rounds of the BMW Championship, let two late bogeys at Crooked Stick Golf Club ruin what was an otherwise solid day.And those bogeys knocked him out of the top five in the FedEx Cup projections for the moment.I couldnt tell you in the last four years at any point in time how many points Ive had, said Spieth, who won the FedEx Cup title last year after capturing the Tour Championship. I dont think about that much. If I get up in the top 10 (at the BMW), maybe I can be in the top 5 (in the FedEx Cup standings). At this point, thats the goal.You want to be in the top 5 going to Atlanta. I dont know what it takes, but I know if Im in the top 10, I should stay sixth (where he began the week). And if I win in Atlanta, it would be hard not to win the FedEx Cup.But not guaranteed, which is why getting in the top 5 is so important.Spieths closing bogeys Saturday, after playing the first 16 holes in 6 under par, knocked him to a projected seventh position in the FedEx Cup standings. So much can alter that on Sunday, including those players around him in the points standings and what they do in the tournament.Tournament leader Johnson is projected to go to No. 1 with a victory here, with Patrick Reed second, Jason Day third, Adam Scott fourth and Paul Casey fifth. If that holdds, any of those players would win the FedEx Cup with a victory at East Lake.ddddddddddddSpieth is not a fan of the system that allows the FedEx Cup champion to be crowned by winning at East Lake while not having necessarily the best season on the PGA Tour.It would be hard to argue with Johnson, Day or Scott capturing the title. All have multiple victories this year. But Reed and Rory McIlroy, who is sixth in the projected standings, have just one apiece. Spieth has two.The FedEx Cup points system gives four times more points during the playoff events than a regular season event. And the points reset after this week, so that all 30 players who make it to Atlanta have a mathematical chance to win the overall title.I dont have the answers to how to do it, Spieth said. It just seems odd that someone can dominate for a year and not win a significant bonus. In order to achieve what they call a yearlong race, more adjustments can be made. But Im happy with the way it worked out last year.If it werent myself or Jason last year (both won five times on the PGA Tour), it would have been something to look at. I think they might have taken a closer look at changing again. Hopefully I can do it again, and maybe they dont look at it again.Sundays final round could also have an influence in other areas.J.B. Holmes (third at the BMW Championship) and Matt Kuchar (tied for fifth) are hoping to get Ryder Cup at-large picks from U.S. captain Davis Love III. So is Bubba Watson, who is tied for 17th.Rickie Fowler, also in need of a pick, is having a tough week. He is tied for 59th and is projected to finish 30th in the FedEx Cup, needing to be among the top 30 to advance to Atlanta. ' ' '
