Right up to the very end of the signing period, apparently, the Washington Redskins plan to continue mining a restricted free-agent market that has been very good to them to this point.

Team officials and agent Drew Rosenhaus confirmed Friday for ESPN.com that the two sides have reached an agreement on an offer sheet for restricted free agent defensive tackle Jermaine Haley of the Miami Dolphins. A three-year veteran, Haley traveled to Washington on Friday morning, passed the Redskins' physical exam and signed the offer sheet.

The deadline for offer sheets to restricted free agents is Friday at 11:59 p.m. ET. After that, their incumbent team gains the exclusive negotiating rights to the player, and he cannot speak to other teams.

Haley is poised to sign a four-year offer sheet worth about $4 million. It includes a $650,000 signing bonus and base salaries of $450,000 (2003), $650,000 (2004), $1 million (2005) and $1.2 million.

The charge on the salary cap for 2003 is $612,500.

Miami will have one week to match the deal. If they match, the Dolphins assume the terms of the offer sheet. If they pass, Haley will move on to the Redskins and Miami will receive a seventh-round choice as compensation. The latter would leave Washington with only three selections -- second-, third- and seventh-rounders -- in this year's draft.

The early expectation is that the Dolphins will not match the offer.

Rosenhaus negotiated late into Thursday night with Washington officials and also with Green Bay Packers representatives. The deal was completed early Friday morning.

Haley, 30, became expendable in Miami when the Dolphins recently signed unrestricted free agent defensive tackle Jeff Zgonina of the St. Louis Rams as the primary backup to starters Tim Bowens and Larry Chester. Miami could still match the offer sheet to Haley and then perhaps attempt to trade him to the Redskins or another interested team.

The Dolphins have about $2.6 million in available salary cap funds, and $605,000 of that counts for Haley, because Miami made him a qualifying offer back in February.

A former University of Washington standout, Haley was originally drafted by the Dolphins in the seventh round of the 1999 lottery, while he was still under contract to the Toronto Argonauts of the CFL. He played through the '99 season in the CFL, then joined the Dolphins for the 2000 campaign.

In three seasons, he has played in 43 games and started nine of them, and has 67 tackles, 2 ½ sacks, one interception and seven pass deflections. Haley is a big-bodied interior defender, strong against the run, and he would provide Washington a solid No. 3 tackle behind starters Dan Wilkinson and Brandon Noble, a hole the team has been trying to fill for more than a month.

The Redskins have already acquired three restricted free agents this spring -- wide receiver Laveranues Coles, free safety Matt Bowen and kickoff return specialist Chad Morton -- through offer sheets that were not matched.
