I really hope this is a worst case scenario. The guy I saw at Pawtucket, was swinging the bat good and appeared to be pain free. Timing was off, but that is fixable.
And again, it was way too early for him to be putting so much pressure on the surgically repaired knee and that is the fault of the crackerjack medical staff.
Who besides us, fields a 200 million dollar roster and hires a 10 cent medical staff?
