Arvidsson exited Saturday's win over the Blackhawks with an upper-body injury and is questionable to play in Detroit. He travelled with the team but his status for tonight's game is unclear.

Caggiula was in the lineup for the last two games but will be replaced by Michael Bunting on the fourth line on Wednesday. Caggiula has been held pointless in his last 11 games.

Kapanen did not return for the third period of Wednesday's game, so his status for the second half of the back-to-back on Thursday is uncertain. Expect an update around 5 PM ET.

Frederic was banged up in the Bruins' last game on March 18th but was on the ice for Wednesday's practice and will be a game-time decision on Thursday. Frederic, who has four goals and one assist in 28 games this season, is expected to play in the bottom-6 but should see some PP2 usage with Jake DeBrusk still out.
