OTTAWA, Ontario (AP) The Ottawa Senators are hopeful that star defenseman Erik Karlsson will be ready for the start of next season following surgery on his left foot Wednesday.

General manager Pierre Dorion says Karlsson's recovery from surgery to repair torn tendons in the foot would take approximately four months.

The 27-year-old Swede was injured during the playoffs, though he still piled up 18 points in 19 games and played 28 minutes per game. Ottawa lost in the Eastern Conference final to eventual Stanley Cup champion Pittsburgh.
