Remaining roof panels will be removed from the storm-damaged Silverdome in Pontiac, Mich., so an entirely new covering can be put on.
The building, whose roof collapsed during a snowstorm March 4, won't be ready for an event until the Detroit Lions play an exhibition football game there in August.
Lane Lambert, right wing for the Detroit Red Wings, underwent arthroscopic surgery to repair injured ligaments in his right knee and probably will be lost for the rest of the season.
Lambert was injured in a collision Friday night in Vancouver. Detroit defenseman Greg Smith, who has missed six games with a knee injury, is scheduled to rejoin the team for its home game against the Kings Wednesday night.
