Boulton (lower body) is on track to play Thursday against the Predators, Arthur Staple of Newsday reports. After completing the Isles' morning skate with no complications, Boulton is set to join the lineup for the first time since Jan. 17. He's still being listed on injured reserve for the moment, but expect the team to rectify that at some point in the afternoon. Boulton, who has appeared in just four games this season while serving primarily as a healthy scratch, is expected to replace the suspended Matt Martin on the Isles' fourth line.
