Pavel Buchnevich was placed on injured reserve with a lower-body injury.
The forward hasn't played since getting one goal and one assist for the Blues in their season-opening 5-2 win against the Columbus Blue Jackets on Oct. 15. He has 78 points (31 goals, 47 assists) in 74 regular-season games since he was traded to St. Louis by the New York Rangers on July 23, 2021.
"He's getting looked at again today and reevaluated today just to try and speed up the process here a little bit," coach Craig Berube said. "It's not serious, but it's aggravating so it's keeping him out of the lineup."
Berube also said Brandon Saad, who did not play Monday in a 4-0 loss to the Winnipeg Jets with an upper-body injury and did not practice Tuesday, is day to day.
Forward Tyler Pitlick signed a one-year, $750,000 contract. The 30-year-old was with the Blues on a professional tryout contract in training camp. He had five points (one goal, four assists) in 39 games for the Calgary Flames and Montreal Canadiens last season.
"Good to have a job and go from there, looking forward to getting in and playing. It should be good," Pitlick said. "It's just been going on a while with the extra time here so yeah, it's a little nerve wracking and you never know if it's going to happen until you actually sign your name on the paper, so it's a relief and excited to get going."
Pitlick, who suffered a lower-body injury Sept. 27 in a 4-1 preseason win against the Chicago Blackhawks and played Sept. 29 against the Blue Jackets, was released from his first PTO before the Blues brought him back Oct. 16.
"He was having a good camp," Berube said. "He got injured, which was unfortunate for him, but he's the type of player that you can use in a couple different spots. He's a good skater, penalty killer, he knows how to play the game properly. We like his speed and size."
