Ronald Tillery of the Memphis Commercial Appeal reports:

Grizzlies forward Rudy Gay has a mild concussion and could miss Tuesday’s home game against the Los Angeles Lakers.

Team doctors confirmed Gay’s condition today after re-evaluating him. Gay left Sunday’s win at Denver with concussion-like symptoms after he received an inadvertent elbow to the head from Denver center Nene.

Under the terms of the NBA’s new protocol for concussions and other head injuries, Gay will have to satisfy a strict set of criteria before being allowed back on the floor.
