Brett Brown said he’s unaware how long Jimmy Butler will be sidelined with a sprained right wrist.

“I don’t really have any idea of what to expect with Jimmy,” the 76ers coach said about the four-time All-Star swingman around 6:20 Monday night. “I only learned this about an hour and a half ago. I think that probably after the game I can share more information.

“It isn’t something that we are or he is worried about in the sense of this is a lingering, long-term thing."

Monday night’s game against the Houston Rockets at the Wells Fargo Center marked the fifth game Butler had missed after being acquired from the Minnesota Timberwolves in a trade on Nov. 12. It was the first one because of his wrist.

He missed two with a strained groin and two others with an upper respiratory infection.

Butler reported discomfort in his wrist Saturday after a 117-115 loss to the Oklahoma City Thunder. An MRI revealed that it was a mild sprain. The team said he’s day-to-day and lists him as questionable for Wednesday’s game against the San Antonio Spurs.

Corey Brewer, who was in the seventh day of a 10-day contract, started in Butler’s place against the Rockets.

Butler is a four-time NBA all-defensive second-team selection. He ranked fourth in the league in steals at 2.07 per game as of Sunday. He’s also the team’s second-leading scorer with an average of 19.6 points. The Sixers were 2-2 in games without Butler before Monday.
