Boston Celtics head coach Brad Stevens confirmed that center Robert Williams suffered a bruised lower back on Saturday night against the Charlotte Hornets.

Stevens also suggested that the rookie big man could miss a significant period of time, similar to Jaylen Brown's nearly two-week absence in 2018 after suffering the same injury.

Robert Williams attempted a follow-up dunk but his hand slipped on the rim. He wasn't able to brace his fall and landed really hard directly on his back. Luckily, Williams was able to walk off on his own power after being on the floor for a good two minutes.

Williams had all the opportunity in the world to showcase his talents, as he got his first career start on Saturday. The Celtics were already without All-Star center Al Horford, who was dealing with left knee soreness. Likewise, backup center Aron Baynes was also out of commission due to a sprained left ankle. Thus, this is really a tough break for the Time Lord.

The Celtics are dealing with a plethora of injuries right now. In addition to the injuries of their big men, Gordon Hayward has also been out for Boston's past three games after being put under the concussion protocol. Jayson Tatum also reportedly got injured against the Hornets.

Nonetheless, it seems like Boston still has plenty of issues to deal with, especially with nine games remaining on their schedule. Not only do they have a depleted roster, but their players don't seem to be on the same page even when healthy.

Boston has struggled with chemistry issues throughout the year. It certainly doesn't help their case that guys are going in and out of the lineup at this point of the season.
