Even if they rest him these next two weeks... From some research every high ankle sprain is different. It could take anywhere from a week to months to a year. The fastest I saw was 10 days.
I imagine the damage was already done when he came back out and played on it in the Browns game but playing in the San Fran game definitely didn't help.
So are we going to have to deal with a gimp Ben; who cannot run, get outside the pocket, play action, etc.. in the playoffs?
