Josh Manson is expected to be out about six weeks for the Anaheim Ducks with an oblique muscle injury sustained against the Minnesota Wild on Monday.
The defenseman left the game with 40 seconds remaining in the first period of a 1-0 win after he and Wild forward Jordan Greenway each was assessed a roughing penalty. He played one shift in the second period and did not return.
Manson did not play in a 3-2 loss to Minnesota on Wednesday and was placed on injured reserve Thursday. He does not have a point and is averaging 15:46 of ice time in three games this season.
Selected by the Ducks in the sixth round (No. 160) of the 2011 NHL Draft, Manson has scored 97 points (21 goals, 76 assists) in 388 NHL games, all for Anaheim.
