One of the keys to rookie quarterback Robert Griffin III in his rookie season with the Washington Redskins is an offensive line that should keep him healthy and off the ground more often than not. On Day One of training camp, that line took a significant hit.

Right tackle Jammal Brown was placed on the physically unable to perform list with hip soreness, a nagging problem that caused him to miss four games last season.


“You knew it was sore. You knew it could happen at any time, something like this,” coach Mike Shanahan said. “You’re just hoping it’s a little flare-up, nothing major.”

Shanahan said Brown felt sore Thursday morning after running sprints Wednesday. There’s no timetable for his return, and the coach said the next step is evaluating the severity of the injury.

“I think it’s really hard for him. He’s been working extremely hard to get in football shape. He is in excellent shape,” Shanahan said. “He’s got a setback. We’ll get a chance for the doctors to look at it and see how it is.”

With Brown out, Tyler Polumbus took snaps with the first string Thursday. According to Shanahan it’ll be a competition between Polumbus, Maurice Hurt and Willie Smith until Brown is ready.

This could be a chance for Polumbus, signed during last season by the Redskins, to show he belongs.

“He’s very capable. He’s a veteran in this league,” left tackle Trent Williams said. “I don’t see why he can’t step in and we still be going at full stride.”

And having a full training camp to work in Shanahan’s system could be just what the 27-year-old needs.

“Anytime you get more reps and more time in the system it’s better,” he said. “The longer I’m here the more comfortable I get and hopefully the better I play.”
