The team announced the news before Friday night's game against Tampa Bay.
Horton has five goals and 19 points in 36 games this season. A prized off-season free agent signing for the playoff-bound Blue Jackets, Horton underwent shoulder surgery last summer, which caused him to miss the first 40 games this season.

You don't see many. The [Drew] Doughtys, the [P.K.] Subbans, those are guys that create offense from the back and then on top of that ability, the size that he has. In the West you play against some pretty big players, and being able to clear the crease and contain the [Ryan] Getzlafs and the [Corey] Perrys and [Anze] Kopitars and players like that, we're excited about him going back there.
