Head coach Mike Shanahan is going to start working on the 2018 season.

The Redskins announced Tuesday that he will start work as the team’s new head coach on Tuesday.

“It’s been a long time coming, and I’m very excited to get started,” Shanahan said in a statement.

“The Redskins organization has had a tremendous amount of success this season, and we’re very fortunate to have the right guy in place to carry us forward.”

Shanahan will be the third head coach in franchise history to come to Washington.

He joins Tom Coughlin and Sean McVay, who both worked with the Redskins in various capacities.

He’s been on the job since March 3, 2012.

Shanahan was fired as the head coach of the Miami Dolphins on Nov. 4, 2016.

He replaced Joe Philbin.

Shanahan has a 3-7 record in three seasons.

Shanahan’s last job with a team that has a winning record was his one-year stint as the Rams head coach from 2011 to 2013.

He was fired by the team in late January.
