The Calgary Flames, who trail Detroit 2-0 in their first-round Stanley Cup playoff series, will be without one of their top defenceman for Game 3 Tuesday (CBC, 10 p.m. ET).
Robyn Regehr is back on the sidelines after he aggravated a knee injury in a collision with Detroit forward Kris Draper during Sunday's 3-1 road loss.
The six-foot-two, 226-pounder missed Calgary's final two regular season games and the series opener in Detroit with the same injury.
Flames coach Jim Playfair saidhe hopes to have Regehr, 27, back in the lineup for Game 4 Thursday in Calgary.
Regehr collected 21 points in 78 games this season — his seventh in the NHL —and topped Calgary with a plus-27 rating.
Meanwhile, Red Wings forward Todd Bertuzzi was a game-time decision Tuesday. He's recovering from concussion symptoms and has yet to appear in a game this post-season.
Bertuzzi spent most of the season recovering from back surgery, posting three goals and 11 points in 15 games for the Florida Panthers and Red Wings.
Detroit acquired him for forward prospect Shawn Matthias and two draft picks on Feb. 27.
Bertuzzi, a native of Sudbury, Ont., has totalled 226 goals and 540 points in 725 games over 11 NHL seasons with the New York Islanders, Vancouver Canucks, Panthers and Red Wings.
