Stars' Klingberg out at least 4 weeks after hand surgery

Dallas Stars defenseman John Klingberg will be out a little longer than initially expected.

The 26-year-old underwent hand surgery Friday and will be out a minimum of four weeks, head coach Jim Montgomery told reporters. He was originally expected to miss three weeks.

Klingberg suffered the injury during his club's 4-3 win over the San Jose Sharks on Thursday, though it's not clear when it occurred.

The blue-liner sits second on the team in scoring with 13 points and paces the club with six power-play points in 16 games.
