Nets sign Shelden Williams

The Nets have signed with forward Shelden Williams, the team announced Tuesday.

"We are pleased to add Shelden to our roster," general manager Billy King said in a statement. "He is a proven veteran who will add depth to our frontcourt rotation."

Williams signed a one-year contract, sources confirmed to ESPNNewYork.com.

The 6-foot-9, 250-pound Duke product has averaged 4.5 points and 4.0 rebounds per game in five NBA seasons with six teams. He spent last season with the Nuggets and Knicks.

The Nets now have four big men under contract: Williams, Brook Lopez, Johan Petro and Jordan Williams.

They are still chasing Orlando superstar Dwight Howard, while also keeping tabs on Denver free-agent Nene as a possible contingency plan. The Nets also could re-sign Kris Humphries if their first two options fall through.
