San Francisco 49ers linebacker NaVorro Bowman missed the entire 2014-15 NFL season after suffering tears to his ACL and MCL in the NFC Championship Game the year prior. It was a disastrous injury, and some have wondered if it's one he can return from.

On Tuesday, Bowman put some of those concerns to rest. The 26-year-old three-time All-Pro posted a series of videos to his Instagram account, one of which shows him squatting 455 pounds.
