Theodore will miss four-to-six weeks after suffering an ulnar collateral ligament sprain in his right elbow.
The Ducks' first round pick in 2013 suffered the injury in Sunday’s futures game. The 19-year-old defenseman had an outstanding season in the WHL last year, posting 22 goals and 57 assists (79 points) in 70 games. He led the Seattle Thunderbirds in points by 16 while playing on the blueline. He had an outside chance of making the Ducks' roster but was likely going to be left off the team because of Anaheim's great depth at the position.
