42 Al Horford C

Horford (kneecap) remains out Saturday against the Pistons, Jared Weiss of The Athletic reports.

As expected, Horford will need more time to recover from Patellofemoral pain syndrome in his left knee. Aron Baynes should continue starting until Horford is healthy enough to play.

Horford (kneecap) won't play Friday against the Hawks.

As expected, Horford will miss a fourth straight contest while recovering from left knee tendinitis. In his stead, Aron Baynes and Daniel Theis should continue seeing extra run.

Coach Brad Stevens said that Horford won't play Wednesday against the Wizards and will likely miss "at least a few games" while dealing with Patellofemoral pain syndrome in his left knee.

Horford has already missed two games while dealing with tendinitis in the kneecap and can probably be penciled in to sit out at least two more contests based on Stevens' comments. The Celtics are hopeful that the time off for rest will prove beneficial for Horford in strengthening the knee and ensuring it's not a recurring issue for him throughout the 2018-19 campaign. Per Jay King of The Athletic, Stevens also relayed that Horford's top backup, Aron Baynes (ankle), is "at the very best questionable" for Wednesday, so Daniel Theis looks poised to earn a third straight start at center.

Horford (knee) is listed as questionable for Wednesday's game against the Wizards.

Horford has missed the last two games with a lingering left knee injury, and his status for Wednesday's game remains up in the air. Horford's status should be updated again following Boston's shootaround in the morning, but with he and fellow center Aron Baynes (ankle) currently questionable, both Daniel Theis and rookie Robert Williams could be holding down the center position again Wednesday in Washington.

Horford (knee) has officially been ruled out of Monday's game against the Pelicans and, according to Tim Bontemps of ESPN, he's dealing with patellar tendinitis in his left knee.

The big man was initially deemed doubtful, then ruled out, then moved back to doubtful, but the team has now officially confirmed that he'll miss a second straight game. With Aron Baynes also out, look for Daniel Theis and perhaps rookie Robert Williams to pick up increased minutes at center against a Pelicans team with a formidable front line. At this point, it's unclear if Horford stands to miss more time beyond Monday, but Brad Stevens did note that Horford has been playing through the tendinitis for "some time," so it's certainly something to keep an eye on as the week progresses.
