Giants offensive coordinator Kevin Gilbride announced his retirement Thursday amidst speculation that he was about to lose his job.

Mike Garafolo of Fox Sports earlier tweeted a report about Gilbride's retirement. Former Giants receivers and quarterbacks coach Mike Sullivan, who was the Buccaneers' offensive coordinator in 2013 under since-fired Greg Schiano, could be a candidate to replace Gilbride.

The writing appeared to be on the wall for Gilbride after the Giants' offense struggled in a 7-9 season that included quarterback Eli Manning throwing a career-high 27 interceptions. Giants owner John Mara went so far as to say, "I think our offense is broken," in evaluating what went wrong in 2013. He also mentioned he thought highly of Sullivan's work.

While head coach Tom Coughlin received Mara's vote of confidence, the Giants' head coach reportedly was scheduled to discuss his staff with Mara and general manager Jerry Reese on Thursday.
