Devin McCourty has conceded that he might not be back with the New England Patriots for the 2015 season.

The 27-year-old's contract with the club expires next week when the league year officially ends, while the Patriots passed up on the chance to use the franchise tag on the safety to keep him under contract for the next campaign.

McCourty has revealed that he had no idea of the club's intention to use the tag on kicker Stephen Gostkowski, and feels that his five years with Bill Belichick's men could be coming to an end in the near future.

"I really didn't know," McCourty told ESPN. "There was no real information from them on if it was going to be me or [Gostkowski].

"So I was kind of going off of what everybody else was going off, with what people were reporting as far as sources and all that. So, I guess it's more realistic now that [there's] a chance that I might not be back [in New England]."

McCourty has recorded 388 tackles, one sack and 17 interceptions in his five years with the Patriots.
