Washington Redskins linebacker Keenan Robinson is expected to be out three to five months after suffering a torn left pectoral muscle at the start of training camp.
The Redskins were hit with more bad news this week with defensive end Adam Carriker undergoing a third surgery on a troublesome quadriceps tendon that is exptected to keep him sidelined for another four to five months. Carriker suffered the injury in the second game of last season and has not recovered.
Robinson, a fourth-round pick from Texas last year, left practice on Thursday with the pec injury. An MRI was done on his left shoulder area.
Last season, Robinson tore his right pectoral muscle in the 11th game that required surgery. He missed offseason practices during his rehab and recovery before being cleared in time for training camp.
Robinson was expected to contend for a backup inside linebacker spot behind London Fletcher and Perry Riley.
"When we heard the news, man, it's devastating," Redskins linebacker Brian Orakpo said. "But the one thing about it, you don't want to look too sad because that makes his morale down, so we've got to make sure we pick him up."
Redskins coach Mike Shanahan is holding out hope that Carriker will return this season.
"It just was not progressing to where he could get the movement in his legs that would give him a chance to play," Shanahan said. "He could work with the weights, but he just couldn't get the circulation, couldn't get the movement, and that's basically why he's had three surgeries. Hopefully, this surgery will give him the ability to have that type of movement that he needs as a defensive lineman to get in that stance and have that explosion."
