It appears that Mickael Pietrus has progressed to the point where he can start taking the league’s mandatory concussion tests, which are required before a concussed player returns to the court.

Meanwhile, Celtics coach Doc Rivers dropped this nugget of good news for Mickael Pietrus, who may begin his concussion testing today. Pietrus has a Grade 3 concussion but was able to watch Wednesday’s game without the shades and a towel over his head that he wore Sunday against the Miami Heat.

Rivers previously said it might be a week after Pietrus takes the concussion tests before he returns to Boston’s lineup. So it looks like he will not miss the rest of the regular season after all.

Adding Pietrus to the second unit alongside Ray Allen might actually make the bench semi-explosive, at least on certain nights when the tandem is throwing flames.
