Philadelphia Flyers goaltender Dan Vladar (lower body) was activated from Injured Reserve and will start Wednesday's contest against the Columbus Blue Jackets. The Czechia netminder has been out for six games while dealing with a lower-body injury. Across 28 prior starts this season, Vladar has posted a good 16-7-4 record. While he hasn't yet registered a single shutout, the 28-year-old has limited opponents to 2.46 goals while producing a .905 save percentage. The Blue Jackets are on a 6-1-0 run and scored eight goals in their last outing, making this a tough game for Vladar's return to the net.

Columbus Blue Jackets defenseman Denton Mateychuk (upper body) will rejoin the lineup on Wednesday against the Philadelphia Flyers. He has been out for six games due to an upper-body injury. Jake Christiansen will make way for Mateychuk in the lineup. It's been a good sophomore campaign for Mateychuk, as the 21-year-old has tallied 21 points (eight goals, 13 assists) in 44 outings while blocking 63 shots. He will join Ivan Provorov on the second defensive pairing, and the two will be part of the second power-play unit as well. Forward Miles Wood (upper body) will also re-enter the Blue Jackets lineup on Wednesday after missing 12 games, giving the in-form team a further boost.

Ottawa Senators center Stephen Halliday (upper body) won't play in Wednesday's matchup against the Colorado Avalanche. The 23-year-old had a fantastic game on Sunday against the Vegas Golden Knights with two goals and one assist, but Halliday also sustained an upper-body injury during the contest. He is considered day-to-day, with Halliday's first chance to return coming on Saturday night against the New Jersey Devils. Xavier Bourgault is expected to replace Halliday in the lineup after he was recalled from the minors. Having been almost a point-per-game performer in the AHL this season, Bourgault will get an opportunity to play in the NHL for just the second time in his career.

Colorado Avalanche forward Ross Colton (lower body) will miss a third consecutive game on Wednesday night against the Ottawa Senators. He suffered a lower-body injury a week ago and is considered day-to-day. Colorado has been hopeful that Colton will return at some point during the team's current four-game road trip. There are two more stops on the trip: Thursday in Montreal and Saturday in Detroit. With Colton and Gabriel Landeskog (upper body) on the shelf, Victor Olofsson has received an opportunity on the first line. Meanwhile, Taylor Makar has slotted into the third line.
