The Indianapolis Colts are sticking with their newest starting quarterback after reportedly re-signing Jacoby Brissett in the aftermath of Andrew Luck’s retirement.

Brissett was thrust into the role after Colts star Luck shockingly retired less than two weeks before the start of the NFL season.

The 26-year-old Brissett quickly resumed quarterback duties and now has a contract to back it up.

According to the NFL Network, which cited unidentified league sources, the two parties agreed to a two-year, $30million extension.

Brissett will receive a $20m signing bonus, the report noted.

The new deal will secure Brissett through the 2021 season, a report from The Athletic added.

Brissett – who entered the league as a third-round pick by the New England Patriots in the 2016 draft – landed in Indianapolis via a trade in September 2017.

He gave the Colts another option under center with Luck’s status still up in the air as he recovered from shoulder surgery.

“We are in good hands with Jacoby Brissett as our starting quarterback,” Colts head coach Frank Reich told reporters last week.

Brissett completed only 58.8 per cent of his passes in 2017. By comparison, Luck’s percentage was under 60 only twice in his six seasons.
