Report: Brady dealing with collateral ligament sprain in right thumb

The mysterious hand injury suffered by Tom Brady this week in practice is reportedly a sprained collateral ligament in the New England Patriots quarterback's right thumb, sources told Albert Breer of the MMQB.

Despite the injury, which ESPN's Mike Reiss reports included a cut on his hand requiring at least 10 stitches, Brady will get the start in Sunday's AFC Championship Game against the Jacksonville Jaguars. The 40-year-old threw in practice on Friday with the results indicating he was well enough to play.

Whether or not Brady will wear a glove on his throwing hand to protect the injury remains to be seen as the Patriots face the Jaguars' league-leading pass defense.
