The Giants are set to promote offensive coordinator Ben McAdoo to head coach, according to multiple reports late Wednesday night.

The 38-year-old, who has helped quarterback Eli Manning thrive the past two seasons, would become the 18th head coach in Giants football history.

An official announcement from owner John Mara could come as soon as Thursday.

Under McAdoo's watch in 2015, the Giants had the eighth best offense (total yards) in the entire NFL.

A domino effect with league coaches began to fall Wednesday as Hue Jackson became head coach of the Cleveland Browns. Jackson was set to interview with the Giants this week but the Browns acted quickly.

The man McAdoo replaces, Tom Coughlin, had a strong interview with the Philadelphia Eagles earlier this week and has also been linked to the San Francisco 49ers job.

It is likely that McAdoo would retain defensive coordinator Steve Spagnuolo, who also interviewed for the head job.
