The Blue Jackets are holding their breath.
First, let's rewind a few days: we gasped seeing Jones grab his lower back after scoring the overtime winner against Colorado on Thursday. He was apparently whacked by Avalanche forward Carl Soderberg while skating by the net, but Jones was fine and played the next night against Detroit (and scored twice).
And then, after a maintenance day from practice on Sunday, Jones left Monday's win over Montreal after two periods with an upper body injury. Blue Jackets head coach John Tortorella said post-game that Jones "aggravated" something during the game, and they'd get a full report on his status sometime Tuesday.
The Blue Jackets losing Jones for any period of time would be significant. He's tied with defense partner Zach Werenski for second-most goals (14) by a defenseman in the NHL, trailing only PK Subban of Nashville and Dougie Hamilton of Calgary, who have 15 goals each.
