Depends how bad of a roll it was. After his goal in the 2nd half he seemed to run on it fairly easily back to the bench (jabbed or not).
I've done my ankle, tore the ligaments off the bone and could put no pressure on the foot for weeks, could do low impact exercise after a month of recovery (stationery bike) but didn't run on it for 3 months.
They can be bloody painful, but it all depends on whether he damaged any of the ligaments. I've rolled my ankle dozens of times playing soccer (its so easy to do), but only once has to had my off of it for any period of time. You can roll it, immediately hurts but within 10-15 minutes the ankle feels ok again. You'd restrap at that point and go again. I suspect it was more one of those rolls than anything majorly bad the way he was running on it in the 2nd half.
