Starting rehab 4 days after the injury is very quick.
NO it is no quick to start rehab 4 days after the injury, heck I had reconstructive rotary cuff shoulder surgery and the very next morning I started rehab.And seriously, rehab right now could consist of him just getting a range of motion. It's not like he is in there powerlifting. He may not yet be extending his arm completely and freely over his head.
WHAT? That is NUTS. I had a full rotator tear (completely unrelated to Portis' injury, btw) and I went a FULL 2 weeks before doing anything at all. I had to sleep sitting up for the first week to 10 days, and was on serious pain killer meds. Even during the second week, I couldn't even get my other hand into the armpit to shower. I was told I'd be out of work for 6 months, but went back in 3, after busting my nut in rehab. Frankly.... I just don't believe you... I think you must have had a less major surgery. I could do ZERO after my surgery, and I mean ZERO. Couldn't even lay down, on my side ot otherewise. Slept in a recliner, in the upright position. I had a knee done, a thumb rewired, sinus surgery... nothing even came close to the pain and recovery of that shoulder surgery... not anywhere close to it.PS: When they cut the tendon, and scrape the humerous, and use anchors imbedded into the humerous bone, that new connection of ligamnet to bone has to be rested for a period of time, or risk ripping the anchors out. Not buying your story.
