The BYU Cougars defense has suffered a big loss, as head coach Kalani Sitake announced Monday that linebacker Keenan Pili will miss the remainder of the season after he tore his ACL last Saturday in the Cougars’ win over Arizona State.

Not only is Pili a team captain, but the sophomore from Provo is also BYU’s leading tackler through three games with 31. The next closest player, fellow linebacker Payton Wilgar, has 19.

Pili also has 1.5 sacks.

Utah native Ben Bywater is now atop the depth chart at MIKE linebacker. Bywater, a redshirt freshman from Salt Lake City, is third on the team in tackles with 18.
