Allen is a late scratch for Sunday's game due to a knee injury, Rob Fischer of Fox Sports Southeast reports.

EDGE Analysis

Allen reportedly suffered a right knee injury during warmups, which will force him to sit out Sunday. The Grizzlies also plan to bring Zach Randolph off the bench, so Courtney Lee and Matt Barnes are going to run with the starters. It's unclear how severe of an injury this is, so we'll have to wait for further information. For now consider him questionable for Monday's outing with the Wizards.
