Boston Celtics point guard Kemba Walker could be cleared for limited minutes in Tuesday night's home game against the Brooklyn Nets, according to a report from NBC Sports Boston.

Walker has been sidelined since the All-Star break due to a left knee injury. He's been ramping up his activity level in practice and it sounds like he could be close to a return.

If Walker is indeed cleared to play in Tuesday night's game, he'll likely be placed on some sort of a minutes restriction. Marcus Smart and Brad Wanamaker saw their usage rates increase while Kemba was out of commission. Expect their minutes to take a bit of a hit in the event of Walker's return.

Walker joined the Celtics prior to the start of this season, signing a four-year, $141 million maximum contract in free agency. The former UConn standout has played in 46 games with his new team thus far, racking up averages of 21.8 points on 42.9 percent shooting from the field (38.8 percent from beyond the arc), 5.0 assists, 4.1 rebounds and 1.0 steal in 32.2 minutes per outing.

Smart and Jayson Tatum are both listed as questionable for Tuesday's game due to illnesses, according to a report from Jay King of The Athletic:

Tuesday night's Celtics-Nets game is schedule to tip inside TD Garden at 7:30 p.m. ET, with TNT having live broadcast coverage. Boston has won three of its last five outings, while Brooklyn will be looking to snap a four-game losing streak.
