The Mavericks downgraded Cooper Flagg in the latest injury report against the Knicks

In 15 games this season, the 18-year-old forward is averaging 15.5 points, 6.3 rebounds, 3.1 assists and 1.3 steals per game. He logged 33.7 minutes per contest while shooting 45.5% from the field and 29.3% from three-point range.

Flegg’s potential absence would further challenge a Mavericks team still searching for consistency early in the season. Dallas sits near the bottom of the conference and continues to evaluate its rotation amid ongoing injury concerns.

In addition to Flagg, Mavericks center Derek Lively II is listed as probable with a right knee injury. Lively, 21, last appeared in the team’s 138–133 overtime win over the Portland Trail Blazers, finishing with two points, three rebounds, two blocks and one assist in 12 minutes on 1-of-2 shooting.

Lively played only five games this season, three of which were starts. He is currently averaging 4.4 points, 4.6 rebounds, two assists and 1.4 blocks per game while shooting 64.3% from the field in 16 minutes per game.

The injury report comes as the Mavericks begin a three-game homestand. After their contest against the Knicks, they will continue to monitor the health of key players as they try to turn around their early season trajectory.
