Weber State offensive coordinator Timm Rosenbach, who was hired in November, has accepted the same position at UNLV.
Rebels head coach Bobby Hauck made the announcement Wednesday afternoon.
Rosenbach, who is leaving without having ever called a play for the Wildcats, was hired at Weber State on Nov. 21, the same day his former high school and college teammate, Jody Sears, was given a three-year contract extension as WSU's head football coach by athletics director Jerry Bovee.
Rosenbach, a former NFL quarterback and Heisman contender, made his brief stop at Weber State after one season as the offensive coordinator at Montana and coaching stints at New Mexico State, his alma mater Washington State, Eastern Washington and St. Ambrose.
"We're excited to have Timm join our staff," Hauck said in a statement released by UNLV. "I've known him for many years and coached against him on numerous occasions. Having tried to stop his offense as a defensive coach, I know he has good instincts and a really good feel on game day."
Rosenbach said in the statement from the school that he is looking forward to joining Hauck, the former Montana head coach.
"I'm thrilled about the opportunity to not only work for Coach Hauck but also to be part of a program at UNLV that I believe is headed in the right direction," he said. "I'm looking forward to coaching an offense that is exciting for fans and puts points on the scoreboard."
Sears is sad to see Rosenbach, his former high school and college teammate, move on, but "I wish him nothing but the best," he said. "I was disappointed to lose a good football coach. Obviously he's extremely marketable and he's got a great reputation for being a good coach. That's life in our world, in our profession. Coaches come and go."
UNLV's hiring of Rosenbach came the same day that former Weber State head coach John L. Smith, who never coached the Wildcats in a game before leaving for Arkansas last year, was hired at Division II Fort Lewis College in Durango, Colorado.
Sears was out of town recruiting on Wednesday but said he's already started the search for a new offensive coordinator, in between home and high school visits.
"There's a bunch of other good football coaches out there that are going to be potential good additions to our staff," he said. "There are two or three real possibilities that are out there."
But recruiting has to come first, Sears said.
"We only get so many hours and so many days that we have an opportunity to be in recruits' homes, on campuses and in high schools so we're going to take complete advantage of it."
