Dallas also Monday recalled defenceman Aaron Rome from his conditioning assignment with the Texas Stars of the American Hockey League and assigned goaltender Jack Campbell to the AHL squad.
Lehtonen has missed the past five games after being placed on injured reserve retroactive to Oct. 11 when he suffered a lower body injury. In three games this season, he has a 2-1 record with a .953 save percentage and a 1.57 goals-against average.
Campbell made his NHL debut on Sunday night against the Anaheim Ducks, stopping 41 of 47 shots.
