The Anaheim Ducks will be without defenseman Cam Fowler until further notice.

The 24-year-old has a sprained knee, and will have his timeline determined later this week. Fowler left Sunday's game against the Philadelphia Flyers in the first period after playing just 3:36, and did not return.

In the wake of the injury, Anaheim recalled defenseman Shea Theodore from the San Diego Gulls of the American Hockey League.

Fowler has three goals and nine assists in 34 games this season.
