Jackets put Derek MacKenzie on IR
MacKenzie is eligible to return Saturday. He has two goals and an assist in 22 games this season, giving him 24 goals and 32 assists in 258 career NHL games with the Atlanta Thrashers and Blue Jackets.
The 24-year-old Tropp has three goals and six assists in 43 career NHL games, including one assist in nine games this season, with the Sabres.
A third-round pick by Buffalo in the 2007 draft, he missed most of the 2012-13 campaign due to a knee injury.
