ST. PAUL, Minn. -- Minnesota Wild right wing Petr Sykora has a concussion and is out indefinitely.

Sykora took a hit to the head in Saturday's win over the Dallas Stars. In his first season with the Wild, Sykora has already missed six games because of a groin injury. He has two goals and one assist in 10 games.

Also, the team says defenseman Kim Johnsson has been cleared to play again after missing the last seven games because of an unspecified upper body injury. The Wild visit the Toronto Maple Leafs on Tuesday.
