New England Patriots tight end Ben Watson confirmed in a Facebook post that he tested positive for testosterone and has been suspended by the NFL for four games.
Watson, who took the banned substance during his brief NFL retirement this offseason, explained the context behind his use.
"After my contract expired last March I told my doctors I was finished playing, went through a series of medical tests and was prescribed Bio Identical Testosterone Cypionate to assist in healing my body and mind.
"On March 29, nine days after I started therapy, I was randomly tested under our substance policies.
