NFL: Three teams kick off offseason programs Monday

The Cleveland Browns, San Francisco 49ers and Philadelphia Eagles all will start formal offseason preparations on Monday.

Head coaches hired after the end of the 2015 season are entitled to conduct an additional voluntary veteran minicamp. Any voluntary minicamp for veteran players must be conducted prior to the NFL Draft (April 28-30), but no earlier than Week 3 of the team's offseason workout program and after at least one week of the two weeks of Phase One activities that the clubs may hold.

This year six teams will hold voluntary veteran minicamps, the NFL announced Friday.

The Browns, coached by Hue Jackson, the 49ers with Chip Kelly and the Eagles with Doug Pederson all will start formal preparations with Phase One of a three-phase program. The first phase features only strength and conditioning and rehab activities.

The Miami Dolphins and new head coach Adam Gase, along with the New York Giants (Ben McAdoo) and Tampa Bay Buccaneers (Dirk Koetter) have opted to begin their offseason programs on April 11.

All other teams will start their offseason programs on April 18 with the exception of the Carolina Panthers.

Panthers coach Ron Rivera has decided to delay the launch of the team's program until April 25.

As per Article 21 of the Collective Bargaining Agreement, each club's official, voluntary nine-week offseason program is conducted in three phases:

--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.

Each team may hold a rookie development program for a period of seven weeks, which in 2016 may begin on May 9. 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.
