Dallas Stars defenseman Marc Methot underwent arthroscopic surgery and will be sidelined four to six weeks, while center Martin Hanzal has a hand injury that is expected to sideline him three to seven days, the team announced Monday.

Backup goaltender Kari Lehtonen, meanwhile, is out indefinitely due to personal reasons, the team said. The team recalled goaltender Mike McKenna, 34, from their AHL affiliate, the Texas Stars. Dallas did not disclose the nature of Lehtonen's personal situation.
