The Edmonton Oilers announced on Tuesday that defenceman Andrej Sekera underwent surgery for a torn Achilles tendon that he incurred during off-season training.
No timetable was given for the 32-year-old Czech Republic native's recovery.
Sekera appeared in 36 games a season ago for the club, chipping in eight assists. His season began in late December after he missed nearly three months following an ACL tear that he sustained during the 2017 Stanley Cup playoffs.
Taken in the third round of the 2004 NHL Draft by the Buffalo Sabres, Sekera has appeared in 683 games with the Sabres, Carolina Hurricanes, Los Angeles Kings and Oilers.
In his 12 NHL seasons, Sekera has 45 goals and 187 assists.
