ESPN's Brian Windhorst ruled out the possibility of the Boston Celtics, or the NBA's 28 other teams, extracting big man Ivica Zubac from the Los Angeles Clipper

BOSTON — Sam Hauser checked himself out of the Celtics’ game against the Pistons on Monday. He was downgraded on the injury report to questionable to return due to a left ankle sprain.

The Boston Celtics may be without one of their key players in Monday night's game against the Detroit Pistons.

The Warriors are dealing with a host of injury issues amid a slow start to the season, and a recurrence of a concerning Al Horford back issue is one worth noting. The former Celtics big man missed his fourth straight game on Sunday night for Golden State and has suited up in just one game since November 24 after being diagnosed with right sciatic nerve irritation.

Following his first three-game losing streak in two years, Jaylen Brown reiterated a belief he had stated several times before. This was in late October, after a frustrating road loss to the Detroit Pistons. At 0-3, Brown and the Boston Celtics were in an unfamiliar situation. He still wanted to give his young team time.
