Seahawks coach Mike Holmgren revealed the surgery in an interview on KJR-AM on Tuesday morning.

Tubbs has missed all or part of two consecutive seasons with knee injuries, including last season, when he suffered ligament damage in his right knee and required reconstructive surgery. That comes after he had microfracture surgery on his left knee late in the 2006 season.

The team spokesman said Tubbs’ latest surgery was to make sure that his healing was going properly.

“It was not a big deal,” Holmgren told KJR.

“We have to see how it goes with him. If there is a chance I can have him (for the long term by holding him out of training camp) then that is how we will handle it.”

The uncertainty with Tubbs’ future was at least part of the reason the Seahawks drafted Texas A&M defensive tackle Red Bryant in the fourth round Sunday.

The team also signed former University of Washington defensive lineman Larry Tripplett on Wednesday, as well as former Oregon linebacker Wesley Mallard.

The Seahawks also claimed quarterback Dalton Bell off waivers.

Tripplett, 29, spent four seasons with Indianapolis after being drafted by the Colts in 2002. He spent the past two seasons with Buffalo. In 92 career games, he has registered 195 tackles, 8.5 sacks, five forced fumbles, four fumble recoveries and one interception.

Mallard has played for the New York Giants, New England Patriots and Tampa Bay Buccaneers, and was primarily used on special teams.

Bell, who played at West Texas A&M, has no NFL playing experience.

He was signed by the Green Bay Packers in January and recently released.
