The second professional season of Boston Celtics center Robert Williams continues to be hampered by injuries.

On Wednesday prior to the team's game against the Detroit Pistons, Brad Stevens mentioned that the big man will likely remain out through the All-Star break due to a hip ailment.

Williams, who last took the floor on Dec. 6, has played an average of 14.2 minutes per contest this season across 19 outings (one start). The slight increase in playing time from his rookie year has aided him in increasing his numbers to 3.9 points and 4.6 rebounds on a nightly basis, all while shooting 67.3 percent from the floor.

It's worth noting that Williams has been previously said to be “pain-free,” though it is clear he is struggling in his recovery.

Without Williams in the mix, the duo of Daniel Theis and Enes Kanter have handled center duties. Williams is now slated to miss at least the next month, which should make his path to rejoining the Celtics rotation clouded down the stretch of the year.

Boston nabbed the 6-foot-8 big man out of Texas A&M with the 27th overall pick in the 2018 NBA Draft. Viewed as a long-term project, Robert Williams has been limited to short stints when he has been given the chance to take the floor over his first two professional seasons.

A two-time SEC Defensive Player of the Year before departing school, Williams has the potential to become the centerpiece of the team's defense should he stay healthy and get to string strong performances together.
