Marshawn Lynch rehabbing off-site; Seahawks sign Bryce Brown

RENTON, Wash. -- With Thomas Rawls (broken ankle) out for the season, the Seattle Seahawks' running back situation is very much up in the air going into the final three games.

The hope now seems to be that Marshawn Lynch will rehab from surgery associated with his sports hernia injury and return at some point down the stretch.

"He’s going to be continuing to rehab, and he’s going to be rehabbing off-site until he’s ready to get back and start practicing," coach Pete Carroll said. "We don’t have a timeline on that."

Asked why Lynch is not rehabbing at the team facility, Carroll added, "Just think it’s best. It’s best for him."

Lynch had surgery three weeks ago. He last played in Week 10 against the Arizona Cardinals and has carried 111 times for 417 yards (3.8 YPC) this season.

Carroll was asked whether it's reasonable to expect him back before the regular season is over.

"I don’t know," he said. "We won’t know until the work starts happening."

Carroll confirmed that the team is signing running back Bryce Brown, who was on the roster earlier this season but did not play. The 24-year-old has spent time with the Philadelphia Eagles and Buffalo Bills. He's carried 226 times for 1,004 yards (4.4 YPC) in his career.

So where does the run game go from here?

Fred Jackson will continue to be the third-down back, Carroll said. Brown and DuJuan Harris will likely both get carries on early downs in a running back by committee setup. Harris carried 18 times for 42 yards (2.3 YPC) and lost a fumble in Sunday's win over the Baltimore Ravens.

Brown has flashed upside throughout the course of his career but has yet to put it all together.

The hope is likely that the team can pick up wins against the Cleveland Browns and St. Louis Rams. If they lock up the No. 5 seed, perhaps Lynch will be ready to go for the postseason.
