more detailed info from espn:
Payouts and guarantees on portions of the new contract were contingent on Burress partcipating more in offseason workouts and being more involved in team activities.
The Giants have a bye week, so Burress will lose two paychecks under the suspension. He will not be with the team during the bye week and won't be allowed to practice with the team next week. His base salary under the new contract is $2 million. His suspension will cost him $235,294.
Burress was not immediately available for comment. Drew Rosenhaus, his agent, did not immediately return a telephone call by The Associated Press for comment.
The Giants did not specify why Burress was suspended. FoxSports.com, which first reported the suspension, said that Burress did not show up for work on Monday and did not telephone or answer phone messages to explain his absence.
Giants spokesman Pat Hanlon said the team was not confirming or denying any reason for the suspension
that's a helluva fine for missing one day of work. wow.
