SANTA CLARA, Calif. -- San Francisco 49ers cornerback Jimmie Ward is week-to-week with a quad strain, the team announced Tuesday. He left Sundays loss to the Seahawks with the non-contact injury after covering a kickoff in the second quarter.That likely leaves coordinator Jim ONeil to find a replacement for one of the most valuable members of his secondary in time for a visit from Dez Bryant and the Dallas Cowboys eighth-ranked offense Sunday.Ward, the teams first-round draft pick in 2014, was off to a promising start to his third season after transitioning to cornerback full-time. He played slot cornerback and safety during his first two years.Third-year player Keith Reaser and rookie Rashard Robinson are competing to replace Ward should he miss Sundays game, ONeil said. The decision will come down to which player performs better in practice.It keeps you on your toes, Reaser said. You know every practice counts, every play matters, almost as if its training camp or a game.ONeil said, Neither one of those guys has won the job outright. So if they want it to be week-to-week every week, thats on them. If somebody wants to establish themselves ... then go do that. Im all for it.Reaser was drafted in the fifth round in 2014 out of Florida Atlantic. He spent his rookie season sidelined while recovering from an anterior cruciate ligament tear in his knee. He made his pro debut last season before getting the third-most snaps among 49ers cornerbacks in 2016.Missing his rookie year helped Reaser prepare mentally for his chance at playing time.Everybody has a different path in this business, Reaser said. You just try to learn as much as you can and go from there.Robinson, a fourth-round draft pick from Louisiana State, joined the NFL facing questions about a checkered college career and an arrest in connection with a robbery, which was later expunged from his record. He elected to enter the NFL draft instead of transferring to a new school after being kicked off LSUs team.Robinson has a chance to start Sunday against a quarterback he faced in college, Dak Prescott, who played at Southeastern Conference rival Mississippi State. The 49ers drafted Robinson 133rd overall, two spots before the Cowboys took Prescott.The one thing I remember from him at Mississippi State is he was pretty mobile, Robinson said. Just got to out there, just contain him.The 49ers signed receiver and return man Keshawn Martin on Tuesday. He played last season with the New England Patriots. He spent his first three years with the Houston Texans after being drafted in the fourth round from Michigan State.Martin becomes the sixth receiver on San Franciscos active roster. He took the roster spot vacated by Anthony Davis, who announced his retirement Monday. It was the second time Davis retired since June 2015. His first retirement was spurred by a concussion he suffered in 2014.Davis rejoined the 49ers at the starting of training camp after his one-year hiatus. He sustained a concussion before the Week 2 loss to the Carolina Panthers which kept him from playing before his retirement was made official. Buy Air Max Australia .

AUBURN HILLS, Mich. -- For about ten minutes on Sunday night, it appeared the Detroit Pistons had solved the Orlando Magics lock-down defense.Like the rest of the NBA, they will have to keep searching for answers.Orlando gave up 27 points in the first 9:30 but then shut the Pistons down in a 98-92 victory.Im proud of our guys, because that team was averaging 118 points their last three games, and that was on the road, Orlando coach Frank Vogel said. We held them to 92, and most of that was our second-half defense. They were at home, and they got 42 points on 37 percent shooting in the second half.Serge Ibaka scored 21 points and blocked four shots, while Nikola Vucevic added 16 points and eight rebounds.The Magic have held 10 of their last 11 opponents under 100 points.We just changed our mindset, Ibaka said. We knew we could play defense, and now were playing for each other on offense. We knew we could play this well. We just had to keep working.Pistons guard Reggie Jackson made his season debut after missing Detroits first 21 games with knee tendinitis. He had 18 points in 23 minutes. Marcus Morris led Detroit with 21 points.I felt good out there, but I wish we could have gotten a win out of it, Jackson said. I think there might have been a little rust, but I was able to do everything I need to do. I wouldnt be out there if I was going to be physically limited.Orlando won for the third time in four games while Detroit had its three-game winning streak snapped.We were terrible on defense, Pistons coach Stan Van Gundy said. Our offensive numbers were good enough to win, especially against that defense, but we didnt guard anyone. We just didnt want to put in the effort.On Jacksons first possession, the Pistons went to their bread-and-butter play -- he and Andre Drummond running a high pick and roll. Jackson came off the screen and hit a 3-pointer, bringing a cheer from the small crowd. Jackson played the first 5:50 of the quarter as Detroit built a 16-10 lead.Morris had 14 points in the first 7 minutes but didnt get much support from his teammmates.dddddddddddd. The Magic scored 35 points in the second quarter to take a 58-50 halftime lead. Orlando shot 62.5 percent from the floor in the half to Detroits 51.2 percent and only turned the ball over four times.Were starting to see the value of the pass on the offensive end, Vogel said. If we pass with good timing, good intent and good delivery, it will help us shoot the ball, and weve got good shooters.The Magic led by 11 late in the third, but the Pistons narrowed the gap to 78-73 at quarters end. Orlando moved the margin back to double figures with nine minutes left, with the Pistons struggling to get open looks against one of the NBAs best defenses.Ibaka ended a Pistons run with a 3-pointer to make it 90-80 with 5:32 to play, then blocked Drummonds dunk attempt at the other end.Kentavious Caldwell-Pope hit a 3-pointer with 40 seconds left to pull the Pistons within 95-90, but Jeff Green clinched the game with a turnaround jumper.TIP INSMagic: Former Piston Jodie Meeks had seven points in 15 minutes in his second game of the season.
