Jayson Tatum is one tough cookie, or rookie if you may. Early in the Boston Celtics' matchup against the Miami Heat, the first-year swingman dove for the ball, where he ended up crashing his hand onto the floor that resulted in a dislocated right pinkie.

Tatum headed straight to the locker to get it taped, and proceeded to doing nasty things on the floor such as this breakaway slam.

That sure earned him some Tommy points.

This kid's got a lot of fight in him. Considering that the Eastern Conference-leading Celtics are going up against a badly-depleted Heat team who's is a dog fight for the eight seed, it would've been easy for Jayson Tatum to call it a night and make the wise decision.

But no, Tatum opted to show his Celtic pride and proceeded to help in putting the game away for Boston. Apparently, he'd rather earn his rest than just roll over after hurting his pinkie.

For better appreciation on what Jayson Tatum is braving through right now, here's a closer look at his finger that has no business pointing in the opposite direction. It's not for the faint-hearted, folks.
