NEW YORK (Reuters) - Tom Coughlin, who coached the New York Giants to a Super Bowl victory in 2008, agreed to a one-year contract extension through the 2012 National Football League season, the team said Wednesday.

Financial terms of the contract were not disclosed.

Coughlin, who has a 65-47 record during the regular season since taking the reins as Giants coach in 2004, had one year remaining on his previous four-year deal.

"We believe in the job he has done, and we believe in his ability to lead our team in the future," Giants President John Mara said in a statement.

Coughlin also spent eight seasons (1995-2002) as head coach of the expansion Jacksonville Jaguars, where he went 68-60 in eight seasons and twice came within one victory of reaching the Super Bowl.

He led the Giants to a surprise Super Bowl victory in 2008 when his team edged a New England Patriots team that entered the game having not lost a game all season.
