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.
