Former NFL quarterback Brady Quinn, who has spent time with seven clubs, has told CBS Sports that the rash of major player injuries could be because players are taking performance enhancing drugs.

Quinn, taken by Cleveland with the 22nd pick of the 2007 NFL Draft, spent eight seasons in the NFL, throwing for 3043 yards and 12 touchdowns with 17 interceptions over 24 games with Cleveland, Denver, Kansas City, St Louis and the New York Jets.

He also saw pre-season action with Miami and Seattle.

In a podcast on CBS Sports, Quinn said that while he was not basing any claims on knowledge or evidence, he noted supplements such as human growth hormone (HGH) can help players get larger at the expense of making them more injury prone and guessed “40 to 50 per cent of guys are taking something” banned.

“I'm not going to be a whistleblower and I'm not accusing anyone of anything,” Quinn said.

“There's got to be something these guys are taking. That's what I think at least.”

And he thinks it has become easier for players to learn ways around being caught in the NFL's anti-doping test program.

“When you're the starter, you have your annual (test) and you have one surprise (test) or one unknown (test),” Quinn said. “But beyond that, you don't get tested quite as often. It's really the backups or older players.”
