"Colts kicker Adam Vinatieri is very close to signing a one-year deal to remain in Indianapolis. Deal should be finalized tomorrow," Bob Kravitz of WTHR wrote on Twitter early Wednesday morning.
Vinatieri's contract with the Colts expired after the 2017 season, making him eligible for free agency when the new league year begins on March 14.
The oldest player in the league, the 45-year-old Vinatieri would be appearing in his 13th season with the Colts after spending his first 10 with the New England Patriots. He connected on game-winning field goals in each of the Patriots' first two Super Bowl wins -- in 2001 versus the then-St. Louis Rams and 2003 against the Carolina Panthers.
Vinatieri connected on 29 of 34 field-goal attempts last season, including five of six from at least 50 yards out. Two of his misses last season came during blizzard conditions in Buffalo.
A three-time Pro Bowl selection, Vinatieri has recorded at least 100 points in each of his past six seasons.
