Not all high ankle sprains are the same. They can vary from mild, week to week, tears, that heal quickly on their own, to severely torn, requiring surgical repair.
And yes, many times return to play is faster after a worse tear, that requires surgery, than a bad, but not quite bad enough for surgery, tear.
Severity of the sprain will dictate when he returns to play, thus the week to week designation initially.
We should have a good idea of the severity sometime in the next couple of days. What I saw didn’t look too bad, but TV angles can be deceiving.
