Supplemental draft pick Jeremy Jarmon and the Washington Redskins agreed to a four-year contract with a $755,000 signing bonus Monday.
The Redskins chose the defensive end in the third round of the NFL supplemental draft on July 16. He was the only player picked.
The 6-foot-3, 277-pound Jarmon was declared ineligible for his senior season at Kentucky by the NCAA because he tested positive for a banned substance.
Jarmon finished third in Kentucky history with 17½ sacks.
Never miss a local story.
He is the first player the Redskins have taken with a supplemental selection. The team relinquishes its third-round pick in the 2010 NFL draft.
Getting Jarmon is the latest move by Washington aimed at upgrading a pass rush that ranked last in the NFC in 2008 with only 24 sacks. The Redskins opened free agency by landing All-Pro defensive tackle Albert Haynesworth, then drafted Texas defensive end Brian Orakpo in the first round.
Orakpo still has not agreed to a contract. Redskins players are scheduled to report to training camp Wednesday, with the first practices slated for Thursday.
