Browns begin offseason workout program

Work for the 2013 season officially begins for the Cleveland Browns on Monday.

Under the collective bargaining agreement, activities are limited to strength and conditioning and physical rehabilitation for the next two weeks. Here are some of the strict rules: Only strength and conditioning coaches, who have no other coaching responsibilities with the team, are allowed on the field with players and no footballs are permitted to be used, except that quarterbacks may elect to throw to receivers provided they aren't covered by another player. Helmets also can't be worn.

The Browns get a head start on the rest of the AFC North because teams with new coaches can begin their offseason programs early. Cleveland's first voluntary minicamp starts April 16, while the other division teams have to wait until May 21 to begin their minicamps. Each player will receive at least $175 per day for any workouts or classroom instruction, according to the CBA.

Mandatory minicamps for all teams are in June, and training camps start in late July.
