Allen is questionable to play Monday versus Brooklyn due to a left ankle sprain, Evan Dammarell of FearTheSword.com reports.
Allen was listed as questionable ahead of the Cavaliers' last game Saturday with the same injury, but he proceeded to suit up and recorded 26 points and 16 rebounds over 31 minutes in a 117-101 win over the Spurs. The Cavaliers haven't indicated that the 25 year-old suffered a setback coming out of Saturday's contest, but his status for Monday's game will still warrant monitoring leading up to the 7 p.m. ET tipoff.
