Cooper Flagg is listed as day-to-day with a left shoulder injury after he left Friday's game against the Pacers in the second quarter. The Mavericks are already without five players, so another frontcourt absence would leave them thinner.

What happened

Cooper Flagg went to the locker room in the second quarter of Friday's game at Indiana with an apparent left shoulder injury, Grant Afseth of DallasHoopsJournal.com reported. The injury report at 8:48 PM ET on Fri, Oct 23 lists the 19-year-old forward as day-to-day with a shoulder injury on his left arm. He had no status before this entry. Earlier this month he was day-to-day for rest on Wed, Oct 14 and was cleared on Fri, Oct 16. No further details on the injury have been announced.

What it means for the Mavericks

Flagg got hurt at Indiana in the 7:00 PM ET game on Fri, Oct 23. Dallas is 0-1 and 10th in the West after one loss. Flagg scored 32.0 points in 32.9 minutes in his only game this season, with 5.0 rebounds and 2.0 assists. Last season he averaged 21.0 points, 6.7 rebounds and 4.5 assists in 70 games. If he sits, the minutes would go to the rotation behind him: P.J. Washington (30.6 minutes), Naji Marshall (28.7), Max Christie (28.5) and Zaccharie Risacher (27.1). Dallas is 0-1 with him and has not played without him. Jett Howard, Caleb Martin, Tarik Biberovic, Dereck Lively II and Santi Aldama are all out.
