Radek Martinek signs with Islanders

With Lubomir Visnovsky on injured reserve, the New York Islanders have signed veteran defenseman Radek Martinek to a one-year deal.

The deal is worth $600,000, a source confirmed to ESPNNewYork.com.

An eighth-round pick by the Islanders in 1999, the 36-year-old Martinek has registered 107 points in 473 career games. He collected three goals in 13 games with the Islanders last season.

Visnovsky was placed on IR earlier this week with a concussion.
