SEATTLE – The NFL announced the league’s voluntary off-season workout days on Thursday, with the Seahawks beginning as soon as May 12.

Seattle’s rookie minicamp lasts from May 12-14, with a mandatory team minicamp beginning June 6 and ending June 8. The team is hosting organized team practice activities on May 22, May 24-25, May 30, June 1-2 and June 12-14.

The NFL’s collective bargaining agreement notes each team has a nine-week off-season program, which is broken up into three phases.

Phase One is the first two weeks of the program, where players can be in the building for meetings, strength and conditioning and physical rehabilitation.

Phase Two, the next three weeks of the program, includes on-field workouts of an individual or group nature. While team offense cannot play against team defense, players can simulate play without contact at a walk-through pace.

Phase Three is the final four weeks of the off-season program, where teams can hold their OTAs and can participate in seven-on-seven, nine-on-seven and 11-on-11 drills.

Dates of off-season workouts are subject to change at the discretion of each team, the release said.
