Linebacker Myles Jack is the latest Bruin to suffer a season-ending injury.
UCLA star LB Myles Jack is out for the season due to a knee injury, coach Jim Mora confirmed Wednesday morning. The injury is believed to have occurred at practice Tuesday, a source told FOX Sports.
The 20-year-old junior, a three-year-starter, is the team's No. 3 tackler and helped seal the Bruins' win over BYU last week with interception in the final seconds of the game. UCLA will visit unbeaten Arizona on Saturday in Tucson.
