New Jersey Devils center Travis Zajac could miss the first four months of the season after having surgery Thursday to repair a torn left pectoral muscle.
Zajac was injured during offseason training last week, and the Devils said his recovery is expected to take 4-6 months.
The Devils open their season Oct. 7 against the Colorado Avalanche.
Zajac, 32, had 45 points (14 goals, 31 assists) in 80 games last season. He has missed 20 games during the past five seasons.
Zajac has 435 points (155 goals, 280 assists) in 779 games in 11 NHL seasons with New Jersey. His best season was 2009-10, when he had NHL career highs of 25 goals and 67 points.
New Jersey selected Zajac with the No. 20 pick in the 2004 NHL Draft.
