Two teams have stayed in contact with Burress' agent, Drew Rosenhaus, about the availability of his client while the receiver finishes his prison sentence.
Burress' release date still is pending, but Rosenhaus expects him to be available for the start of training camp.
"I'm very confident that Plaxico will be playing next season in the NFL," Rosenhaus said in a text message.
Rosenhaus declined to specify the two teams interested in Burress. But last offseason, the New York Jets explored the possibility of signing him and some around the league thought the Giants would be open to bringing him back.
Washington also is expected to be looking for a receiver. But according to Rosenhaus, Burress already is square on the radar of two NFL teams.
Burress went to prison in September 2009 for violating New York's stringent gun laws and was expected to serve 20 months with credit for good behavior. Burress comes up for potential full release on June 6, 2011. He also will be on probation for two years.
The charges stemmed from an incident in the fall of 2008 in which Burress accidentally shot himself in the thigh at a Manhattan nightclub with a gun that had not been licensed in New York.
