The Seahawks' offseason program begins in earnest on April 21st, will last nine weeks, and will be separated into three phases. The three phases, as explained by an official press release by the NFL, are:

Phase One consists of the first two weeks of the program with activities limited to strength and conditioning and physical rehabilitation only.



Phase Two consists of the next three weeks of the program. On-field workouts may include individual player instruction and drills as well as team practice conducted on a "separates" basis. No live contact or team offense vs. team defense drills are permitted.



Phase Three consists of the next four weeks of the program. Teams may conduct a total of 10 days of organized team practice activity, or "OTAs". No live contact is permitted, but 7-on-7, 9-on-7, and 11-on-11 drills are permitted.



Article 22 of the Collective Bargaining Agreement stipulates that clubs may hold one mandatory minicamp for veteran players. This minicamp, noted below, must occur during Phase Three of the offseason program. Head coaches hired after the end of the 2013 season are also entitled to conduct an additional voluntary veteran minicamp.



Each club may hold a rookie football development program for a period of seven weeks, which in 2014 may begin on May 12. During this period, no activities may be held on weekends, with the exception of one post-NFL Draft rookie minicamp, which may be conducted on either the first or second weekend following the draft. The dates of the post-draft rookie minicamps will be circulated at a later date.

As stated, the team is allowed to hold an additional Mini-Camp for rookies and a few select veteran-type players that haven't accrued a season in the NFL (and I think there are a few other rules that allow them to bring non-contract players in on a tryout basis). The Hawks held their rookie mini-camp last year on May 10th, but this year it will be either on the weekend of May 17th or May 24th.
