Gruden is set to become the next head coach of the Oakland Raiders.
It had been reported from a number of media outlets that Gruden would return as coach and receive a formal introduction Tuesday during a news conference.

Jon Gruden has been a staple of Monday Night Football ever since joining ESPN in 2009, but he'll be heading back to the NFL coaching ranks soon enough.
The 54-year-old spent seven seasons as the Bucs coach, but was sacked following the 2008 campaign after a 9-7 term.More news: Kabul blast: Death toll rises to 20
The Raiders, meanwhile, have gone through nine different head coaches since firing Gruden. After a brief hiatus, Brown returned to football as the part owner, coach and general manager of the AFL expansion Cincinnati Bengals, who began play in 1968.
McDonough brought up Gruden leaving the broadcast booth three times before the first quarter ended, and each time Gruden awkwardly laughed and deflected. Shell went 2-14 that season and was sacked after one year. He led the Buccaneers to the Super Bowl title over Oakland the following season.
He spent his first four seasons as a head coach with the Raiders and went 38-26 with two playoff appearances from 1998 through 2001.
Besides the emotional pull of coming back to the franchise where he made his name, there is cold logic behind the Raiders' pursuit of Gruden.More news: Paris Hilton gets engaged and the ring is HUGE
