The Celtics' official Twitter reported on the matter:
Gerald Wallace will not return to tonight's game after bruising his right knee.— Boston Celtics (@celtics) November 5, 2013
New head coach Brad Stevens already has a modest rotation to work with in his maiden season at the helm, and while this looks to be only a minor setback, losing Wallace isn't ideal.
Boston was 0-3 before Monday's road trip to Memphis' FedExForum. Even though Wallace has scored as many as 19.4 points per game in the 2007-08 season, he did not take a single shot in 28 minutes of action before exiting.
Although he may have a point, perhaps Wallace should assert himself more on the offensive end if this team is going to remain competitive in the midst of a perceived rebuilding year.
