Sources - Tariq Woolen has knee surgery, out until Seahawks training camp - ESPN

Seattle Seahawks Pro Bowl cornerback Tariq Woolen underwent arthroscopic knee surgery Tuesday that is expected to sideline him until training camp, league sources told ESPN.

Woolen, a fifth-round draft selection last year who tied for the league lead with six interceptions as a rookie, injured his knee while walking on the practice field for OTA's one week ago.

Doctors reviewed the injury, and Woolen's surgery, which took place in Houston, went as well as doctors could have hoped, according to a source.

Woolen is expected to be ready for the start of training camp in late July, but the Seahawks also will proceed carefully with their prized cornerback, according to sources.

Seattle also recognized it needed more depth at the position and re-signed former cornerback Artie Burns to a one-year deal Monday.

The Seahawks also used their top pick in last month's draft on Illinois star cornerback Devon Witherspoon, who they envision teaming up with Woolen to dominate the cornerback position for seasons to come.
