"They have indicated that they intend to trade him and are trying to do so," agent Jerome Stanley said in an email exchange with ESPN.com.
Northcutt joined the Jaguars as a free agent in 2007 and in 29 games caught 88 passes for 1,146 yards and six touchdowns. He also did some work as a return man. He came into the league as a second round pick by Cleveland out of Arizona in 2000.
The Jaguars have already parted ways with two receivers who they once valued as first-round draft picks. They were uninterested in re-signing Reggie Williams, a free agent, and released Matt Jones, who'd gotten in off-field trouble. They also cut 2007 free agent signee Jerry Porter.
Jones, Northcutt and Williams combined for 146 of the team's 335 receptions in 2008.
Rebuilding Jacksonville signed Torry Holt, after he was released by St. Louis. First-year general manager Gene Smith also spent three of the team's nine draft picks on receivers: Mike Thomas, Jarett Dillard and Tiquan Underwood.
