UCLA linebacker Zach Whitley has not practiced with the team for the last week, but head coach Jim Mora said the true freshman is still on the team.

Mora did not disclose the reason for Whitley’s absence. Earlier this month, the coach refuted reports that he had dismissed the former four-star prospect, rated a top-100 recruit nationally this past spring.

Whitley enrolled at UCLA in January after decommitting from Alabama and performed well in camp, but suffered a concussion in August that may have stunted his development. The 6-foot-1, 220-pound defender played in nine games this season and made one tackle.
