The Boston Celtics haven't had a full complement of players to begin the season, but it appears they could get a much-needed reinforcement in the backcourt soon. According to Keith Smith of Yahoo Sports, Kemba Walker is inching closer to making his season debut with the Celtics.

Walker has been out for Boston's first 11 games of the 2020-21 season due to a left knee injury that he suffered last season. Amid his absence to start the season, the Celtics have used an assortment of players like Jeff Teague, Payton Pritchard, and Marcus Smart to replace him in the starting lineup.

In addition, Jaylen Brown and Jayson Tatum have seen expanded roles on the offensive end of the floor. Both Brown and Tatum are recording career-highs in points per game as Tatum leads the Celtics with 26.9 points per game.

The news of Walker being questionable for Sunday's game versus the New York Knicks is a step in the right direction for Boston. The veteran point guard has been ruled out of every game thus far, which shows that he's made enough progress to near a return.

Seeing that the Celtics have been playing well without Walker in the lineup, Brad Stevens may choose to be cautious with Walker. Even if he does suit up on Sunday against the Knicks, he likely won't see huge minutes.

And if Walker is ruled out for his 12th straight game, then his next chance of making his season debut for the Celtics would come next Wednesday against the Philadelphia 76ers.
