Metacarpal recovery time?

Hi folks, I recently broke my 5th metacarpal in training (just unlucky, the club has an excellent safety record), fortunately it's a clean break at the base of the hand, alignment all correct, no op necessary. But I'm 2 weeks into a 6 week long cast, and wondering from the good people here what to expect in terms of recovery of the hand muscles and integrity of the bone after the cast comes off?



Basically the question is, how long should I wait before using the hand again for bag work and light-contact sparring?



TIA
