Raiders officially announce Jack Del Rio head coach

Nearly 24 hours after most of the world knew Jack Del Rio was the Raiders head coach, the Raiders have officially made it official.

"After a thorough interview and evaluation process, we are excited to announce Jack Del Rio as the head coach of the Oakland Raiders," said Owner Mark Davis in a press release. "I have no doubt that he will make a significant impact and help reach the goal of everyone in this building, which is to win championships."

"Jack Del Rio brings a strong leadership presence to this organization," General Manager Reggie McKenzie added. "He has developed an excellent reputation as a coach in this league and we are happy that he is a Raider."

There were some who speculated perhaps the lag time before the announcement could be due to the Raiders hoping to have some other members of the coaching staff in place as well. That is not the case as yet per the announcement.

Del Rio's introductory press conference will happen Friday afternoon at 1:00pm Pacific Time.

Here is Del Rio's coaching resume:

1997 New Orleans Saints Assistant Strength Coach
1998 New Orleans Saints Linebackers
1999-2001 Baltimore Ravens Linebackers
2002 Carolina Panthers Defensive Coordinator
2003-11 Jacksonville Jaguars Head Coach
