Former HLN Anchor Carlos Diaz, suddenly popped up on KPHO’s ‘Wake Up Arizona’ as co-anchor.

Diaz was most recently a co-host on CBS’ KXNT Radio, a gig that lasted less than a year when, according to our sources, he was abruptly terminated.

Along with radio and HLN, Diaz did  a stint at Extra, and some time at ESPN.

Late yesterday, KPHO posted his bio on the station's website, it makes no mention of his failed radio gig in Sin City.
