San Francisco 49ers quarterback Jimmy Garoppolo is going to play at

least one possession in the preseason opener Thursday night against the Dallas Cowboys Cheap Zack Martin Jersey , coach Kyle Shanahan said."He'll play somewhat into the first quarter. We'll see how long the opening drive is," Shanahan said Tuesday.Garoppolo will be taking his first snaps in a game since signing a five-year, $137.5 million contract in February. Garoppolo has looked good during training camp, including Tuesday's practice when he hit receiver Aldrick Robinson for a pair of touchdowns during full-team drills.Shanahan said he hasn't determined which veterans will play and which will be given the night off.Cornerback Richard Sherman was ruled out earlier after suffering a hamstring injury during practice Friday. He spent Tuesday doing conditioning drills and will be re-evaluated next week when San Francisco returns to practice.Former first-round pick Jimmie Ward is expected to start in Sherman's place despite also missing recent practices with a hamstring injury.

But Cooper hasn't had enough time in practice to play against the Cowboys."He's not able to get through a practice yet," Shanahan said. "We're just putting him in, I want to say it's two plays a period. We're very selective with those plays we put him in. Just trying to build back his confidence from coming off his injury."Shanahan said the game will dictate how many snaps the defensive starters get."It's kind of a feel. We don't want to keep them out there too long, but we definitely want guys to get some reps Cheap Cole Beasley Jersey ," he said. Dak Prescott accepted the challenge.The Dallas quarterback threw a 64-yard touchdown pass to Tavon Austin on the third play of the game and the Cowboys sacked Eli Manning six times in a 20-13 victory over the New York Giants on Sunday night.The Dallas defense was strong again, just as in an opening loss at Carolina, as the Cowboys (1-1) avoided the first 0-2 start in seven seasons under coach Jason Garrett.Manning and the Giants have started 0-2 for the fifth time in the past six seasons.After saying "challenge accepted" during the week to Giants safety Landon Collins' suggestion that New York had a better chance by forcing Prescott to throw, the 2016 NFL Offensive Rookie of the Year hit Austin in stride behind cornerback Janoris Jenkins. The speedy receiver cut back to his right before trotting across the goal line at an angle."We definitely hear that," Prescott said. "I kind of said the challenge accepted, I said I accepted it. But I can tell you I wasn't the only one who accepted that challenge. This team accepted it. That offense accepted it. We wanted to go out there and just show you guys."Dallas running back Ezekiel Elliott outgained Saquon Barkley in the first meeting in the pros between the former college rivals and high NFL draft picks. Elliott, who starred at Ohio State, rushed for 78 yards with a touchdown.

New York also lost center Jon Halapio, who was carted off with an air cast on his right leg in the third quarter.Manning converted a pair of fourth downs on sneaks, but the sacks helped keep the Giants from converting those into points. He was even hammered when he wasn't behind the line of scrimmage — on a hit by linebacker Jaylon Smith on a 1-yard gain before New York's first points on Aldrick Rosas' 28-yard field goal late in the third quarter."Eli's confident," coach Pat Shurmur said. "He's a pro and he battled throughout the game and I thought he did a good job. I sense confidence, yes."Prescott fooled the New York defense several times with fake handoffs to Elliott on keepers around end. The longest was a 15-yarder on Dallas' second possession, leading to Maher's first NFL field goal from 37 yards.For the second straight week, the Giants didn't get a touchdown until the fourth quarter.

He struggled to find much room outside of a 19-yarder on the second scoring drive. The touchdown was a churning 6-yard run for a 20-3 lead with 5:45 remaining.DELAYED DEBUTDallas tight end Rico Gathers was active for the first time in his third NFL season.
