NFL Media's Ian Rapoport, citing a team source, reported Friday that talks are underway with the league's oldest head coach.
The 64-year-old Carroll signed a three-year deal after he led Seattle to the Super Bowl XLVIII title.
A new contract would put to rest speculation that Carroll might be prepared to retire after the 2016 season.
Carroll is 60-36 and has led the Seahawks to the playoffs five times, including the last four seasons.
Carroll was originally named the Seahawks' head coach on Jan. 9, 2010 after a nine-year (2001-09) run at the University of Southern California, including back-to-back national championships in 2003 and 2004.
