Wings trim 7 from roster
Each assignee played for the Griffins last season with the exception of Oulahen, a rookie who spent the last three seasons with Brampton of the Ontario Hockey League.
The seven join four other players who were assigned to Grand Rapids by Detroit earlier this week. Forwards Eric Himelfarb and Todd Jackson (Wed.) and goaltenders Logan Koopmans and Drew MacIntyre (Fri.) have already taken part in Griffins training camp practices.
Griffins training camp continues this afternoon with an intrasquad scrimmage at 4 p.m. at Griff's IceHouse at Belknap Park.
