WALTHAM, Mass. -- Boston Celtics guard Isaiah Thomas sat out Wednesday's off-day practice because of soreness in his left (shooting) wrist, but said he expected to be in uniform for Thursday's game against the visiting Milwaukee Bucks.

Thomas said his wrist swelled after he fell on it "a few times" during Monday's loss to the Minnesota Timberwolves. Thomas didn't seem himself during that game, struggling with his 3-point shot (2-for-7) and reluctant to drive at the basket (no free throw attempts). He finished with 18 points on 8-of-20 shooting overall.

The Celtics took Tuesday off and the team's medical staff held Thomas out Wednesday as a precaution. Boston's All-Star guard observed the team's practice from the sideline, and president of basketball operations Danny Ainge was seated next to Thomas during the brief portion open to the media.

Thomas admitted that part of the precaution might stem from the fact he has undergone surgery on his left wrist in each of the past two offseasons, including a clean-up procedure eight months ago.

"[The Celtics' medical staff] wanted me to sit out and rest it [Wednesday]," Thomas said. "It got swollen on me the other night. Just being real cautionary because I've had two procedures on it. Just trying to get the swelling out."

Added Thomas: "I fell on it a few times. And usually it doesn't hurt for how long it did and, when we got off the plane the other night, it was still painful and a little sore. Just trying to ice it and get as much treatment as possible."

Thomas was adamant he wouldn't miss any games because of the injury.

"I'm not sitting out," he said. "I'm playing all 82."

Thomas, who earned his first All-Star appearance this month, is averaging career highs at 21.6 points, 6.8 assists, and 2.9 rebounds in 32.4 minutes per game. Thomas has appeared in all 58 games for Boston, including 55 as a starter, a role to which he was elevated after filling a more familiar sixth-man role following his arrival in Boston last February.

Celtics coach Brad Stevens likewise downplayed any concern about Thomas' wrist.

"It was sore enough that we sat him out [Wednesday], but we expect him to play [Thursday]," Stevens said.

Pressed on if there was any long-term worry, Stevens added, "We would not play him if it was a long-term concern. No way."
