The Red Wings won an important playoff game but lost a very valuable defenseman.in the process.

Danny DeKeyser, who had made such a positive impression late in the season, broke his thumb in the third period of Thursday's 5-4 overtime victory.

Coach Mike Babcock confirmed after the game DeKeyser is likely miss the remainder of the playoffs.

"He's done," Babcock said.

DeKeyser, from Macomb and Warren DeLaSalle, was unavailable for comment.

DeKeyser, 23, was an undrafted college free agent who left Western Michigan after his junior season and signed with the Red Wings on March 30. In 11 games with the Red Wings, DeKeyser had one assist and earned a plus-4 rating.

A defensive defenseman with good range and mobility, DeKeyser quickly earned the confidence of Babcock and the rest of team's veterans. In his playoff debut in Game 1 Tuesday, DeKeyser played 19 minutes 31 seconds and had three hits and two blocked shots. Thursday, DeKeyser wound up with 16:15 and had two hits and one blocked shot.

"When we lost DeKeyser, that was a big blow," Babcock said.

Babcock has several options to go to with DeKeyser unavailable.

Veterans Ian White and Carlo Colaiacovo, along with rookie Brian Lashoff, have been healthy scratches the last week of the regular season and the start of the playoffs.
