Stars forward Janmark has joint disorder in knee

FRISCO, Texas (AP) Dallas Stars forward Mattias Janmark will possibly miss all of the season because of a joint disorder in a knee.

Stars general manager Jim Nill said Friday that Janmark has Osteochondritis dissecans, a joint disorder where bone underneath the cartilage dies because of reduced blood flow.

The 23-year-old Janmark, from Sweden, is expected to be sidelined 5-6 months. He had 15 goals and 14 assists in 73 games as a rookie last season.
