Blackhawks forward has history of back trouble

Chicago Blackhawks: Forward a href="http://sports.espn.go.com/nhl/players/profile?statsId=1283">Eric Daze will undergo additional diagnostic tests on his stiff back, general manager Mike Smith said Monday.

Daze has been out of the lineup for the last three games. He has undergone surgery twice to repair herniated lumbar discs during his career.

Without Daze, the team has gone 1-2. They snapped a four-game losing streak with a 3-1 win Sunday night.

Smith said the results of the tests on Daze will be released when they are available.

Minnesota Wild: Defenseman Willie Mitchell is day-to-day after spraining a ligament in his right knee.

An MRI revealed the mild sprain on Monday.

Mitchell, one of the Wild's best defenseman, suffered the injury during Minnesota's 3-1 loss at Dallas on Sunday. He sprained the knee when Dallas forward Steve Ott checked him hard along the boards during the first period.

Mitchell was lining up Bill Guerin for a hit when Ott collided head-on with him. He missed the rest of the game. He'll be a game-time decision when Minnesota hosts Calgary on Tuesday night.

In other news Monday, the Wild placed left wing Jeremy Stevenson on waivers to make room for right wing Richard Park, who was activated for Sunday's game against the Stars. Park missed five games after tearing a ligament in his right knee during an exhibition game against St. Louis on Oct. 1.

Stevenson, who played a key role for the Wild last season after being recalled from Houston of the AHL in December, has been squeezed out with the emergence of rookies Brent Burns and Christoph Brandner.

If Stevenson isn't claimed by Wednesday morning, the Wild will reassign him to Houston.
