Sebastian left the Bears' 44-30 defeat to No. 22 Northwestern Saturday in the second quarter with an apparent leg injury. First-year Cal coach Sonny Dykes confirmed Tuesday that Sebastian tore his Achilles tendon, and will undergo season-ending surgery Thursday.
"It's tough for him. Avery's a kid that loves to play football, has a tremendous passion for the game," Dykes said, per the San Jose Mercury-News. "He'll be back better than ever."
A junior, Sebastian is expected to apply for a medical redshirt. Fellow junior Michael Lowe is projected to replace him in the Bear starting lineup.
Sebastian had already overcome a serious head injury suffered in fall practice, one that reportedly left him immobilized for as long as 15 minutes and sent him to the hospital for an overnight stay. Despite missing two weeks of practice, he recovered in time to start against the Wildcats and had made 11 tackles before being injured early in the second quarter.
