I have a couple of questions for you about a broken foot. In my WIP, my main male character broke his foot. About how long would it be before he could be up on stage in a rock concert? He's the lead guitarist of a Christian rock band and is quite active during the show (running around, etc).
First, I'm assuming you mean a bone in the foot is actually broken and not the toe itself.
After the first two weeks, he should be able to walk and bear weight but jumping around may still be difficult. Probably could go either way. If he does choose to do a concert-- at least have the foot be painful during/after the performance.
