What are workout bonuses and how do they count against the Salary Cap?

Workout bonuses are bonuses paid to players for attending offseason workouts. Starting on the first day of the league year, teams will have to carry a Cap charge of that minimum daily rate x 80 players x 36 days of offseason workouts. For 2013, that number equals $504,000.  At the end of offseason workouts, that amount is removed from the team’s Salary Cap and replaced by the actual amount of workout bonuses paid to players.
