The thing about being seven feet tall is that doorways can sometimes, well, get in the way.

Celtics rookie Fab Melo suffered a concussion last weekend after bumping his head on the doorway in his Sioux Falls hotel room while the Maine Red Claws (Melo’s NBA Development League assignment) were in South Dakota for back-to-back games against the Skyforce.

Melo was seen by the Red Claws medical staff and did not play in the team’s Monday afternoon game. On Wednesday, the Celtics recalled him to be evaluated by team doctors that night.

The center donned a button down shirt and dress pants to join his Celtics teammates in the locker room prior to their game against the Memphis Grizzlies. He does not know when he will be able to sport a uniform — there is no timetable set for his return.

“I still have a little headache,” Melo said. “Sometimes I can’t really focus on something for a long time, that’s it.”
