Does anyone believe he will only be out a short length of time with a broken foot. Sometimes it takes a year before recovery. Frank Thomas missed most of two years and he wasn't trying to escape defenders or carry 240 lb linebackers.
Looks to me like he is done for the year.
Depends where the break is on the foot. If it was a relatively clean break, the bone can actually be stronger than it was pre-break, but I'm with you, I find it hard to believe that he will be an effective runner anytime soon.
