Cincinnati Bengals' C.J. Uzomah is making amends with a fan after messing up his phone during an end zone celebration this weekend ... by hookin' him up with a new one -- AND tickets!!!

If you missed it, the Bengals TE knocked fan, Sebastian Day's, phone out of his hand while trying to high five supporters after scoring a 4th-quarter touchdown against the Detroit Lions on Sunday.

Bengals RB Joe Mixon noticed the oopsie, picked up the phone and took selfies before giving it back to Day ...  and the whole moment went viral!
