Well, here's what Rotowire has to say. I'd tend to believe what they are predicting. They don't want Davis re-injuring himself.
Rotowire via Yahoo! Sports wrote:Update: Davis, who has missed the past two games following surgery on his knee, practiced for the third straight day on Friday and said afterward that he felt "great." Davis is listed as questionable, but expects to play Sunday at Denver, the Charlotte Observer reports.
Recommendation: While this is good news for Davis owners, Carolina could be going with a shared-backfield approach Sunday. Coming off knee surgery, it's highly unlikely the Panthers will give Davis 25-30 carries this week. Expect more like 15-20 touches for each of DeShaun Foster and Davis. As such you should adjust your expectations of either accordingly.
