The pinky finger was pointing the wrong way and swelling up, according to Rapoport. Burrow was able to throw and came back into the game. He doesn't plan to miss time, but it remains to be seen how hard he can throw the ball and how accurate he can be, Rapoport went on to say. Allen is the backup to Burrow.

Bengals QB practiced in full again Friday and will be available if needed against the Houston Texans, according to Geoff Hobson of Bengals.com.

It is great to see Allen did not suffer a serous knee injury when he went down two weeks ago. Ryan Finley played well against a stout defense Week 15, and gets an easier matchup against the Texans Week 16.
