Detroit Red Wings center Luke Glendening could miss the start of training camp after having surgery Monday on his left ankle to repair tendon damage.
Glendening's expected recovery time is 3-4 months.
"The surgery was done to repair an injury he suffered late in the season," Red Wings general manager Ken Holland said Tuesday. "We hoped he would improve with rest and immobilization, but we decided at this point that surgery was necessary to make sure he is ready for the 2017-18 season."
Glendening, 28, broke his ankle and partially tore tendons during the Red Wings' 4-3 overtime win against the Carolina Hurricanes on March 27 and missed the final seven games of the regular season. He had 14 points (three goals, 11 assists) and was minus-10 in 74 games.
Glendening has 60 points (24 goals, 36 assists) in 293 career NHL games, all with the Red Wings.
