Washington Redskins head coach Jay Gruden announced Friday that starting tight end Jordan Reed will sit out Sunday's 2014 home opener against the Jacksonville Jaguars.

Reed – a third-round pick of the Redskins in 2013 – strained his hamstring seven plays into the Redskins' season opener against the Houston Texans Sept. 7.

"One leg was on the ground and the other leg that was in the air snapped forward and that's when it happened," Reed told the media on Friday. "I didn't feel it until I stood up."

Reed has already battled his fair share of injuries during his short time in the league. Since being drafted by the Redskins, he has missed time due to an injury to his quad, a concussion and now an injury to his hamstring.

"It's just frustrating, man," he said. "It's just one thing after another. (I've) just got to keep positive, just keep grinding and hopefully things will turn out for me."

Gruden said Thursday that the team will play on Sunday with just two tight ends, Logan Paulsen and Niles Paul – something they have been preparing for all offseason.

"Luckily for us we practiced in the offseason and training camp a lot of different personnel groupings just in case something like this happens so we're not handcuffed and panicked – 'Oh my god, we lost a player, what are we going to do?'" Gruden said. "We're prepared for it. We're prepared to go no tight ends, we're prepared to go two tight ends, three tight ends, four tight ends. We can put a big guy at tight end. So we're well prepared."

Reed said he's hoping to get back onto the field as soon as possible.

"All three injuries I've had are just kind of fluke things," he said. "It just kind of happens – nothing I could really do. I've just got to let it take its course and work hard on coming back as I fast as I can."

Other injuriesGruden on Friday announced two other players – linebacker Akeem Jordan and cornerback Tracy Porter – were also out for Sunday's game against Jacksonville at FedExField.

Both Jordan (knee) and Porter (hamstring) suffered their injuries in the preseason.

Gruden also ruled veteran defensive lineman Kedric Golston – who's battling a groin injury – doubtful for Sunday's game.

With nose tackle Barry Cofield now on IR and Chris Baker moving from defensive end to nose tackle, Gruden acknowledged the team will be stretched thin with potentially five defensive linemen dressing against the Jaguars.

"I think they might have to play a little bit more than they're used to, but I think they're in good shape – Jarvis [Jenkins], [Chris] Baker, [Jason] Hatcher – I think all those guys can be ready to roll, [Frank] Kearse has got a chance to be active," Gruden said. "We have the able bodies, it's just a matter of going out and playing and staying hydrated and still working a good rotation."

Kearse, a third-year defensive end out of Alabama A&M, signed with the Redskins in May, and eventually impressed the coaching staff enough to earn a spot on the final 53-man roster.

"He's one of the young guys that you didn't really expect to emerge like he has so far," Gruden said. "Now it's just a matter of going out on a game day, if he's chosen to do so, and going out and producing."

Gruden said Kearse had a strong preseason, and if he plays Sunday, hopes those performances will translate into success during the regular season.

"That's what you have to do when you're a rookie trying to make a team or a second-year guy trying to make a team, as a free agent type guy, take advantage of your reps and make your presence known, and he did that and that's why he's here," Gruden said. "We have confidence in Frank, and hopefully he's ready to roll."
