So apparently it's common knowledge (and common practice) that Ben Roethlisberger could receive a pain-deadening injection in his injured throwing shoulder this weekend in order to get back on the field and be effective there.
Meanwhile, a sketchy Al Jazeera report alleges Peyton Manning was prescribed HGH after his neck surgery in 2011 in order to, well, get back on the field and be effective there.
HGH was banned by the NFL in 1991, but at the time of Manning's alleged use it had no testing protocols for it. In any case, if it's true (which remains extremely debatable), Manning was using HGH for the exact same reason Roethlisberger, if he chooses to do so, will use painkilling injections this weekend.
So why is the former regarded by the NFL as a performance-enhancing drug, but not the latter?
