Arizona athletic director Greg Byrne resorted to social media to announce the hiring of Rich Rodriguez as the school's new football coach on Twitter.

Byrne posted on his Twitter account a picture of himself with Rodriguez, wearing an Arizona baseball cap, the coach's wife and two children. The tweet said: "And the new Arizona football coach and his family is ..."

A press conference will be held Tuesday at 2 p.m. ET.

FootballRumorMill.com reported via Twitter that apparently, there were "complications" in discussions with former Oregon coach Mike Bellotti. A person told TucsonCitizen.com that Bellotti turned down an offer from Arizona.

Rodriguez, 48, was 60-26 in seven seasons at West Virginia, from 2001 to 2007, winning four Big East titles.

Rich Rodriguez was let go after three seasons at Michigan.

He failed to duplicate that success at Michigan as he tried to implement his fast-paced read-option style of offense. Rodriguez was 15-22 with the Wolverines before being fired after last season, in a case of he just might have been the wrong guy at the wrong time.

While he was at Michigan, the program was placed on three years of probation for violations of practice and training regulations.

His departure from West Virginia was messy, as the school sued to collect on his $4 million buyout in his contract. The suit ended up being settled.

Rodriguez has the right quarterback to make his offense work right away -- athletic senior-to-be Matt Scott, who will be able to finish out his redshirt season Saturday against Louisiana-Lafayette.

Interesting to note that current Arizona quarterbacks coach Frank Scelfo was on the same staff as Rodriguez at Tulane under Tommy Bowden in the late 1990s.

Arizona announced late this afternoon that, contrary to usual procedures on a Monday, there would be no post-practice interviews for coaches or players.

Arizona has been looking for a replacement for Mike Stoops, who was 41-50 before being fired at midseason. Rodriguez has been an analyst for CBS Sports this season.
