ATLANTA, Dec. 31 -- The Atlanta Thrashers placed veteran defenseman Adam Burt on injured reserve Sunday with a herniated disk in his lower back that will keep him out of the lineup at least a week and could require surgery.
Burt, who turns 32 on Jan. 15, was injured in the first period of Friday's 5-2 road loss to the New York Islanders.
He will undergo treatment for seven to 10 days, after which time doctors will determine if surgery is needed.
Since missing the first six games of the season with a fractured cheekbone, Burt has two assists, 27 penalty minutes and a plus-2 rating in 27 contests.
The 6-2, 210-pounder signed with Atlanta as a free agent in July and provided veteran leadership on a largely inexperienced defense. Veteran Gord Murphy has not played at all this season and could be forced into retirement due to a shoulder injury.
All-Star defenseman Petr Buzek has been out since the second week of the season with a neck strain and concussion-like symptoms and Yannick Tremblay aggravated a leg injury in Thursday's 4-1 victory over the New York Rangers.
To fill Burt's roster spot, the Thrashers recalled defenseman Brett Clark from Orlando of the International Hockey League, where the 24-year-old has two goals and seven assists in 34 games.
