Redskins tight end Fred Davis, who’ll be a free agent after the season, cost himself plenty of future money via a four-game suspension, since it puts him one bad Friday night away from a one-year suspension.

Redskins tackle Trent Williams, the fourth pick in the 2010 draft, won’t have to worry about free agency for several more years. But he’ll still be losing plenty of money under the big-money contract he signed last year.

For starters, four game checks won’t be paid to Williams. At a base salary of $7.852 million for 2011, that’s $1.847 million in lost pay.

Beyond that, Williams could lose a portion of his $3 million signing bonus and, under the new CBA, a piece of his 2011 $7.5 million roster bonus. Specifically, Williams could forfeit 25 percent of the $300,000 signing bonus allocation for the current league year, along with 25 percent of the $1.5 million roster bonus allocation for the current league year.

The actual forfeiture of money already paid to Williams will depend on the language of his contract. The prior CBA permitted forfeitures only of signing bonuses. The new CBA permits a partial forfeiture of roster bonuses, if a breach occurs in the year the roster bonus was earned.

Since Williams’ contract was signed before the new CBA was finalized, his contract likely doesn’t contain specific language permitting a partial attack on the roster bonus. However, plenty of pre-2011 contracts contain language authorizing the maximum forfeiture permitted by the labor agreement.

Ultimately, a fight could emerge over whether Williams’ roster bonus can be attacked absent specific language in his contract contemplating forfeiture. In the end, the outcome would hinge on the terms of the contract and the manner in which a grievance would be resolved.

To summarize, Williams will lose at least $1.847 million. He probably will lose another $125,000 of his signing bonus, and he could lose another $375,000 of his roster bonus.

That’s a maximum potential loss of $2.347 million. All because Williams chose marijuana (or whatever banned recreational substance he was using) over football.
