The Dallas Stars can't seem to catch a break.
Shore's injury occurred in the same game in which Alexander Radulov made his return to the lineup after a six-game absence. The Stars recently lost defenseman John Klingberg for a month due to a hand injury.
Shore isn't a household name league-wide, but he entered Monday in a tie for fourth on the team in points with 11 and had enjoyed success skating on the team's top line alongside Tyler Seguin.
The 24-year-old was Dallas' second-round pick in 2012.
