Schefter did not specify what Schuplinski's role will be with the Colts, but I would guess he would become the new quarterbacks coach in Indianapolis.
Patriots offensive coordinator Josh McDaniels is now the Colts' new head coach.
McDaniels saw an opportunity to make amends for his first head coaching experience.
He is the 26th coach in franchise history, replacing Chuck Pagano, who was sacked December 31 after missing the playoffs for the third straight year.
That was evident in the past two Super Bowls and this season's AFC Championship Game, when the Patriots were hit with three different moments of adversity. Congrats to Doug Pederson of the Eagles on beating almost 10 percent of the National Football League head coaches on Sunday.
Some hires this coaching season - Matt Nagy to the Bears, Patricia to the Lions - might have caused a little buyer's remorse based on the final game of the season.
The Colts ranked 23rd in Adjusted Offensive Net Expected Points (NEP) per play and dead last, at 32nd, in Adjusted Defensive NEP per play last season.
But there will be no finger pointing at the offense when it comes to the Patriots Super Bowl loss.
The Colts announced McDaniels' introductory news conference will take place Wednesday.
A lot of McDaniels' success relies on what the future holds for Andrew Luck.
The conspiracy theory was that if Belichick is leaving the Patriots, McDaniels may want the job. Patricia has been in the running for the post for several weeks but the move could not be made official until after the Patriots' Super Bowl defeat.
There is a slight chance McDaniels might pull out of the running for the Colts job, which explains Pats receiver Danny Amendola's answer about losing his offensive coordinator.
