Adams exited to the locker room in the fourth quarter of Sunday's game against the Pelicans due to an apparent left leg injury, Will Guillory of The Athletic reports.

Adams appeared to suffer the injury while attempting to block a Zion Williamson layup attempt. Adams had to be helped back to the locker room, and if he's unable to return, he would finish with five points (2-3 FG, 1-2 FT), 10 rebounds and two assists over 27 minutes. Dorian Finney-Smith and Clint Capela are candidates to play more in Adams' absence.

Williams (knee) won't play Sunday against Sacramento, Casey Holdahl of the Trail Blazers' official site reports.

Williams was added to the injury report earlier in the afternoon due to left knee injury management, and he's since been downgraded to out. The big man's absence likely will open up some playing time for Yang Hansen behind Donovan Clingan.

Kalkbrenner is not in the Hornets' starting lineup against the Nuggets on Sunday.

Kalkbrenner started in Saturday's loss to the Warriors and finished with four points (2-3 FG, 0-1 FT), seven rebounds, three assists and two steals over 24 minutes. The rookie second-rounder will revert to the bench Sunday while Moussa Diabate reenters the Hornets' starting lineup following a one-game absence due to a hamstring injury.

Adams is starting Sunday's game against the Pelicans, Lachard Binkley of SI.com reports.

The Rockets have elected to move Adams into the starting five with Tari Eason (ankle) set to miss another matchup. Adams has been a strong rebounder in his last five appearances as a starter, averaging 8.8 rebounds in 27.6 minutes per game.

Embiid is listed as questionable for Monday's game against the Pacers due to left knee injury management.

Embiid may miss the front end of this back-to-back set as the Sixers continue to manage his availability. The star big man has yet to suit up in both halves of a back-to-back this season, so he'll likely sit out one of Philadelphia's next two outings. Over eight appearances this month, Embiid has averaged 26.3 points, 7.1 rebounds and 3.5 assists in 32.3 minutes per game.

Porzingis (Achilles) has been ruled out for Monday's game against the Bucks.

Porzingis will miss a sixth consecutive game while recovering from left Achilles tendinitis. His next chance to play is Wednesday against the Grizzlies, though there doesn't appear to be a clear timeline of return for the veteran big man. Mouhamed Gueye will continue to serve as the Hawks' backup center behind Onyeka Okongwu for as long as Porzingis is sidelined.

Boucher (back) is questionable for Monday's game against the Pistons, John Karalis of BostonSportsJournal.com reports.

Boucher was a late scratch Saturday due to back spasms, but he'll have a chance to be available Monday if he continues to trend in the right direction. Even if cleared to play, he's unlikely to see the court.

Hayes (hamstring) is available for Sunday's game against the Raptors, Dan Woike of The Athletic reports.

Hayes has missed LA's last three games while dealing with left hamstring tendinopathy, but the team has given him the green light to take the court Sunday evening. He'll come off the bench with Deandre Ayton also set to return from a brief one-game absence.

Ayton (knee) isn't listed on the injury report ahead of Sunday's game against the Raptors, Dan Woike of The Athletic reports.

Ayton took a seat for Saturday's clash while dealing with knee soreness, but he's ready to roll Sunday. The big man is averaging close to a double-double in January, putting up 11.5 points and 9.1 rebounds over eight appearances.

Williams is listed as doubtful for Sunday's game against the Kings due to left knee injury management.

The Trail Blazers play the second leg of their back-to-back set Sunday, so Williams will likely be sidelined in order to manage a lingering left knee injury. Yang Hansen and Duop Reath should both see a bump in minutes Sunday, assuming Williams is sidelined.
