Tennessee Titans wide receiver A.J. Brown is one tough cookie. The 23-year-old proved just that in a recent Instagram live video, as Brown revealed how he's actually been playing through a serious injury from early in the campaign.

Brown was in a hospital bed in his live video, as he shared how he just had surgery on both of his knees (h/t Emily Proud of WKRN):

It is worth noting that Brown's injury from Week 2 was officially listed as nothing more than a bone bruise. As it turns out, the injury was much more serious than reported. The fact that Brown played through what the doctors had already deemed as a season-ending injury only makes his 2020 campaign even more impressive.

Brown had quite a few things to say in his video, including an impromptu admission of his desire to see out his career in Tennessee:

That's exactly the stuff Titans fans want to hear from their star WR. He's literally committing his future to Tennessee on a hospital bed after a couple of hours of surgery. If that isn't loyalty and dedication then I no longer know what is.

Brown and the Titans' season came to a bitter end after bowing out to the Baltimore Ravens, 20-13, in their Wild Card matchup. Brown, who was a doubt to even suit up for that matchup due to an ankle issue, admitted prior to the game that he was breathlessly anticipating the playoff battle. While the All-Pro WR came out with an impressive performance for the Titans, his effort still fell short as Tennessee was outplayed by a determined Ravens side.
