Jaylen Brown is back in the Celtics lineup for Sunday’s game against the Bucks

BOSTON – Jaylen Brown will be back in the Boston Celtics lineup for Sunday afternoon’s game against the Bucks in Milwaukee.

Brown is officially available for Boston after missing the last four games with a left hip flexor strain. Celtics head coach Joe Mazzulla said Brown will not be on a minutes restriction against the Bucks.

Brown hasn’t played in more than a week, last playing for the Celtics on Nov. 1 in a road win against the Charlotte Hornets. The Celtics took a 3-1 lead with Brown out of the lineup.

This season, Brown averaged 25.7 points, 7.2 rebounds, 3.8 assists and 1.5 steals in his six games for Boston. He shoots 40 percent from the floor overall, but only hits 26.7 percent of his attempts from downtown.

Jaylen Brown’s hip injury

The Celtics dealt with Brown on a daily basis after he had to sit out the second leg of a game against the Hornets in Charlotte. He said the Boston Globe last weekend that the injury had been bothering him since training camp and that fluid had recently been discovered on his hip during an MRI.

The Celtics maintained that Brown’s injury was nothing serious, but he missed a key game against the Golden State Warriors in Boston on Wednesday night. That was the team’s only loss while Brown was out as the Celtics lost 118-112 to Golden State.

The Celtics won road games against the Hornets and Atlanta Hawks and defeated the Brooklyn Nets on Friday night at TD Garden without Brown in the lineup. Boston is 8-2 this season heading into Sunday’s game against the 2-7 Bucks in Milwaukee.
