Lagesson played in two straight games, registering an assist in 17:17 on Wednesday but will come out of the lineup on Friday. Chris Wideman will be back in the lineup to replace him.
Copp will miss his second straight game with a lower-body injury but the Rangers are hopeful that he will be ready for Game 1 of the playoffs.
Copp left Tuesday's game with a lower-body injury and will not play on Wednesday. Some other regulars will also sit out on Wednesday, so it's unclear if Copp's injury is serious or if this is a precaution.
Copp was hurt against the Islanders last Thursday after scoring a first period hat-trick. He missed Saturday's game in Boston but was on the ice for Monday's practice and will be a game-time decision on Tuesday. Since joining the Rangers at the trade deadline, Copp has scored eight goals with 10 assists (18 points) in 15 games.
Copp scored a hat-trick in the first period but then left with a lower-body injury against the Islanders on Thursday and is not expected to play Saturday in Boston. With both Copp and Filip Chytil (undisclosed) not likely to be available, look for two of Jonny Brodzinski, Greg McKegg and/or Julien Gauthier to draw into the lineup.
Chiasson missed the last two games with a non-COVID illness but will play Thursday in Minnesota. Chiasson has been red-hot as go late and should be back in a top-6 role and on the top PP unit.
