When he had the surgery the doctors said 6-9 month recovery time ( end of Feb-end of May range). The 6 month is the best case scenario the way Drew Brees recovered. But Brees just had his recovery. He wasn't taking classes and rehabbing for the second year in a row. Dr. Andrews who did both Brees and Braxton has said he's never seen anyone recover as quick as Brees. Dr. Andrews tells every patient who has labrum surgery and whose paycheck/future relies on throwing that odds are their career is over ( throwing). Obviously there are success stories like Brees but far more patients are done competing at a high level after that surgery. Think about Brees. He had the labrum tear and was sent into free agency and only two teams offered him a deal..Saints and Dolphins.
Only thing we can guess on now is that Braxton's timeline has shifted closer to the 9 months if not further out. If you go and dig back through all the comments Urban/Braxton and other coaches have made since the surgery you'll notice little tidbits have been mentioned like how Braxton has missed some targets on things like throwing a nerf ball and being able to raise his shoulder.
IMO still will be shocked if he ever plays QB again for Ohio State. Less than 8 months to VaTech and he's not even close. And that's just the healing part. Take a look at a photo of him right before the injury and then on the sideline in Dallas. He's lost so much weight/muscle in his upper body. He's just got a lot of work ahead of him to just play football again... let alone throw the ball around.
Wish him nothing but the best... Go Bucks!
