Ritchie missed five games before returning to the Bruins lineup on Tuesday but his infection has popped back up. Patrice Bergeron is expected to be back in the lineup to replace Ritchie.

Ritchie missed five games before returning to the Bruins lineup on Tuesday but his infection has popped back up. Patrice Bergeron is expected to be back in the lineup to replace Ritchie.
Bergeron has missed the last two games but is expected to play vs. the Sabres. Bergeron will likely replace Brett Ritchie, who is dealing with an infection and comes in with six goals and five assists (11 points) in his last nine games.
With Mike Green and Patrik Nemeth not expected to play on Thursday, Hicketts joins the Red Wings in Columbus. The 23-year-old has two assists in five NHL games this season and is second among Griffins' defensemen with nine points (all assists) in 11 AHL games.
Smith has missed the last two games and was moved to IR to make room for Joe Hicketts to be recalled from Grand Rapids (AHL). Smith is eligible to return whenever he is healthy.
Helm was forced to leave Tuesday's game vs. the Senators but could play in Columbus on Thursday. If Helm can't play, look for the Red Wings to go with 11 forwards and seven defensemen.
Green left Tuesday's game with an upper-body injury and is expected to miss their two-game road-trip in Columbus and New Jersey. Joe Hicketts was recalled from Grand Rapids (AHL) and is expected to replace Green on Thursday.
Nemeth got an infection from blocking a shot vs. the Golden Knights and is expected to miss his fifth straight game on Thursday. Nemeth is hopeful he can return to the lineup in New Jersey on Saturday.
With Nick Foligno returning from a suspension, Nash will serve as a healthy scratch vs. the Red Wings. Nash has just one assist in his last nine games.
Foligno will replace Riley Nash in his return to the lineup and will look to get things going offensively. Foligno has scored just one goal with six assists in 17 games this season.
Brouwer was in St. Louis on a PTO but with Sammy Blais going down for at least 10 weeks, they elected to sign the veteran winger to a one-year deal. Brouwer was last with the Florida Panthers, where he had 12 goals and nine assists (21 points) in 75 games in 2018-19.
Blais suffered the injury during the Blues' 3-1 win over the Tampa Bay Lightning on Tuesday. Blais will be re-evaluated in 10 weeks, which means he could miss more than two and a half months. To replace Blais, the Blues announced that they've signed veteran Troy Brouwer to a one-year deal.
Devan Dubnyk missed Wednesday's practice for personal reasons, so Kahkonen comes up and will likely serve as Alex Stalock's backup on Thursday.
Dubnyk missed Wednesday's practice to deal with a "family issue" and is questionable for Thursday's game. Alex Stalock is coming off of a win in Buffalo on Tuesday, so they won't hesitate to let Dubnyk have the night off with Stalock starting and Kaapo Kahkonen backing him up.
