NEW YORK — Former New York Giants Super Bowl star Plaxico Burress is to get out of prison in June, after officials agreed Friday to shave about three months off his time behind bars in a gun case.

A committee of prison-system staffers decided Burress was eligible for time off for good behavior, so he can be freed after serving about 21 months of his two-year sentence, system spokeswoman Linda Foglia said.

With Burress’ release date now set for June 6, his agent and lawyer said he’s looking to return to football — and a number of teams are looking at him.

“He’s counting the hours,” lawyer Peter M. Frankel said. “He’s extremely positive.”

NFL Commissioner Roger Goodell has ruled that Burress would be reinstated and eligible to sign with a team upon completing his sentence. While the league and players are locked in negotiations that have cast a shadow of uncertainty over the sport’s next season, Frankel and Burress agent Drew Rosenhaus said several teams had expressed interest in the receiver.

“The future is very bright for Plaxico,” Rosenhaus said in an e-mail.
