Detroit Lions linebacker DeAndre Levy has been increasingly outspoken about the NFL, brain injuries and CTE over the past month on his Instagram account.
He's questioned the NFL multiple times, from why the league has chosen to employ certain doctors to funding questions. On Monday, he continued focusing on the issue, challenging Indianapolis Colts owner Jim Irsay's comments comparing the risks of playing football to taking aspirin, among other things, when it came to the post-playing effects of football in an interview with Sports Business Journal.
