Seattle Seahawks defensive end Patrick Kerney had surgery on his left elbow on Tuesday in Seattle to remove bone chips. Team sources characterized the surgery as maintenance cleanup. Kerney is still expected to be ready in time for training camp in July.

KING-5 first reported the story.

Kerney had season-ending, shoulder surgery in 2008, missing the last nine games of the year. Kerney’s had two major shoulder surgeries in less than a year, tearing the labrum in his left shoulder for the second time since signing with the Seahawks.

Kerney injured the shoulder during an Oct. 26 victory over the San Francisco 49ers.

Kerney initially had arthroscopic surgery, and indications were that the injury was not severe. But he continued to have problems.

When doctors did the more extensive surgery, they learned he had torn the labrum, which is a cuff of cartilage around the shoulder socket that makes the shoulder more stable.

The Seahawks signed Kerney to a six-year, $39.5 million contract in 2007, with $19 million guaranteed. As Seattle’s best pass rusher, he commands double-teams and makes those around him better. However, Kerney finished the year on the injured reserved for the second time in three seasons.

Kerney did not participate in the pre-draft, mincamp and isn’t expected to participate in any of the off-season minicamps leading up to training camp in July.
