Marshawn Lynch has finished up his first week of practice with the Seattle Seahawks after four years away from the team. Seattle coach Pete Carroll said it's undeniable that Lynch's return provided some energy.

Lynch will play on Sunday night when Seattle faces San Francisco with the NFC West title on the line. Carroll would not divulge how much Lynch will play. It will likely be three backs splitting the playing time with Lynch, Robert Turbin and rookie Travis Homer sharing the load.

Neither Lynch nor Turbin have played in a game since October of last year.
