The Sioux Falls Skyforce announced a tweak to their roster on Friday.  Guard Casey Mitchell will be on the inactive list and be replaced by center Chris Ayer.

Mitchell was recently signed by the Skyforce after playing in Europe early in the season.  Sioux Falls still held the rights to Mitchell after he left the NBA Development League in February of 2012.

Ayer was traded to Sioux Falls from the Maine Red Claws in exchange for Curtis Jerrells after the Skyforce picked Jerrells from the player pool.  It will be the first appearance for Ayer in a Skyforce uniform this season after averaging 6.8 points and 3.2 rebounds in 37 games with Maine.
