Commodore and Babcock talked on Friday, and the coach said he is excited.
"We had him earmarked for two weeks,'' Babcock said. "We like his size and he's physical. He's a perfect fit for our team. He'll support his teammates, he'll work hard on people.
"If he's paired with (young) Jakub Kindl, he'll help him.''
Commodore, who played regularly on Carolina's Stanley-Cup winning team in 2006 and the Flames team that lost to Tampa Bay in the 2004 Cup finals, said he's excited to play for a talented puck-possession team.
"I'm not a rushing defenseman but can hold my own moving the puck. I look forward to getting the puck to (the forwards), kill penalties, block shots,'' Commodore said. "That's one thing Ken and Babs said the Wings needed -- someone to be hard to play against.''
Commodore has played 454 games over parts of nine NHL seasons with New Jersey, Calgary, Carolina, Ottawa and Columbus, picking up 23 goals, 81 assists and 645 penalty minutes.
Commodore got to know Holland last summer at a golf outing in Western Canada. Holland called him "a good person.''
"He's helped Carolina and Calgary in playoff runs,'' Holland said. "He'll work the front of the net to move people out. He's a good guy on the third pair, got a presence to him.
"If we put him in the right situation, he'll play good hockey for us.''
