Cleveland running back Trent Richardson (ribs) will be evaluated on a week-to-week basis, Browns coach Mike Shurmur said according to the Cleveland Plain Dealer. Shurmur pulled Richardson Sunday after just eight carries but didn't give a definitive reason other than saying, "There were some things happening out there where we weren't having efficiency running the football that were no fault of Trent's. But I'm watching the player and we try to make decisions based on what's best."Fantasy Spin:Shurmur said he hasn't ruled out letting Richardson heal and return after the team's bye week. That would mean the rookie would miss home games against San Diego and Baltimore.
