The Stars' $29.5million netminder Ben Bishop left Monday's game against the Ottawa Senators after sustaining a lower-body injury, Dallas announced.
Bishop suffered an apparent knee injury after a collision in front of the net with team-mate Dan Hamuis.
He met with trainers but continued to play until the end of the first period.
Bishop, who is 26-17-4 with a 2.51 GAA this season, stopped 12 shots before leaving after the first period. The Senators won 3-2 in overtime.
Backup goalie Kari Lehtonen started the second period for Dallas and could be in line to start Tuesday against the Predators.
