Petr Mrazek was placed on injured reserve, retroactive to Friday, with a groin strain the goalie sustained in a 4-3 overtime win against the Detroit Red Wings.
"We did that obviously for our roster moves but I know he's going to be seeing the trainers and doctors again today," Blackhawks coach Luke Richardson said Sunday. "He's battled really hard for us this year, too. I think with us, maybe at the end of that second period, gaining a little momentum, too, he didn't want to leave the game, but I think it was a smart move. Hopefully it panned out doing that."
Mrazek saved 15 of 18 shots through two periods, then did not return against Detroit. Alex Stalock played the third period and overtime and saved all 10 shots.
Mrazek was limited to 20 games with the Toronto Maple Leafs last season because of a groin injury.
Stalock started for the Blackhawks in their 5-4 win against the Seattle Kraken on Sunday. Arvid Soderblom, recalled from Rockford of the American Hockey League on Friday, was the backup goalie. -- Tracey Myers
