Horton will not be in the lineup against the Lightning and his status for the final two games of the regular season this weekend are also questionable.
“He’s still day-to-day and he skated this morning, so he’s on the right track,” said Bruins coach Claude Julien. “Day-to-day means he’s not in tonight, but we don’t know where he’s going to be by Saturday’s game, and the same thing with Sunday, so he’s progressing well.”
Horton suffered the injury during a first-period fight with the Pittsburgh Penguins’ Jarome Iginla last Saturday at the Garden.
Overall, Horton has 13 goals and nine assists for 22 points, including a plus-1 rating, in 43 games this season.
