I haven't heard it being mentioned but I would guess that it had something to do with it. Man that stinks. He wasn't even supposed to go but as luck(if you could call it that) would have it, Ray Lewis drops out and Teddy takes what I would guess would be the longest if not one of the longest flights of his life. You have heard of the warnings for people with circulation issues concerning these long flights haven't you. They wouldn't let him talk to reporters upon leaving the hospital. I think it is due to impaired speach. Man what a sad event. The 911 call from his wife can be found on this page...
