Robert Williams suffers knee contusion, doubtful for tonight

Robert Williams is doubtful tonight against Denver
The Boston Celtics got off to a great start last night at the Las Vegas summer league. The Celtics defeated the Philadelphia 76ers 95-89 behind strong efforts from Semi Ojeleye and Guerschon Yabusele.

Rookie Robert Williams didn't start the game but his debut was very promising. He checked in midway through the first quarter and almost instantly provided an impact. Williams threw home a dunk underneath the rim, drilled a contested jumper as the shot clock ticked down, and pulled down an impressive rebound in traffic.
All in all, Williams finished with four points (2/4 FG) and two rebounds in just under six minutes of floor time.

The flashes in his first couple minutes on the court were enough to get Celtics fan giddy. However, as the first frame ended the former Texas A&M center limped over to the bench and eventually to the locker room. Reports quickly came back that Williams had suffered a knee contusion after banging knees with another player. He was relegated to the bench with a bag of ice on his knee for the rest of the night.

It was very disappointing to see Williams' debut be cut short by injury and now it's affecting his availability in Boston's second game against the Denver Nuggets. Jay King of MassLive reported earlier today that Williams has been ruled doubtful for tonight's matchup with the Nuggets.
Considering the fact that it's just summer league, the Celtics are being extremely cautious with Williams' knee. He's already dealing with tendinitis and Boston likely just doesn't want the injury to flare up or worsen in an exhibition game.

Depending on how he heals up over the next few days, we might be able to expect Williams back on Monday night when Boston plays Charlotte.
