By reworking both players' deals, the Bucs freed up approximately $500,000 in cap room.
Dilger, who signed a three-year contract with Tampa Bay last year, caught 34 passes for 329 yards and scored two touchdowns in his first season as a Buccaneer.
According to Dilger's agent, Mark Bartelstein, Dilger's $170,000 roster bonus was turned into a signing bonus, which reduced his 2003 base salary to just $650,000.
Jurevicius, who signed a four-year contract last year and was due a $300,000 roster bonus this offseason, also had his deal reworked in a manner that was beneficial to both he and the Bucs.
"We were happy to accommodate the Tampa Bay Buccaneers' request," said Neil Cornrich, who serves as Jurevicius' agent. "Joe has always been a team player and loves playing for the Bucs. He was more than happy to help team out and he hopes to finish his career in Tampa."
Jurevicius caught 37 passes for 423 yards and scored four touchdowns during the 2002 regular season.
To date, the Bucs have also restructured the contracts of cornerback Ronde Barber, linebacker Derrick Brooks and kicker Martin Gramatica.
The Bucs are believed to be about $550,000 under the salary cap.
