According to Scout.com's Brandon Huffman's twitter feed, UNLV linebacker Jordan Barrett is going to walk on at UCLA. 

Interesting to hear that former Sherman Oaks (Calif.) Notre Dame LB Jordan Barrett left UNLV to walk-on at UCLA...

According to Huffman's tweets, Barrett was rated the #12 outside linebacker in the nation when he signed with UNLV out of Sherman Oaks Notre Dame. He played in all 12 games for the Rebels last season as a tight end.

As an aside, Huffman's twitter feed and his postings on the Scout sites, including Bruin Report Online, are essential reading for UCLA football fans. 

QUICK UPDATE: Gold's Daily News UCLA blog has the story, too. 

After looking at that and glancing at a thread on the BRO premium board, I get the feeling that UCLA didn't even announce Barrett's arrival to the media. They just noticed him at practice and on the roster. Interesting. Gold says Barrett was UNLV's first string H-back. The kid had some early offers from Pac 10 schools, never got one from UCLA (or SC) and went to Vegas. Not sure why he left -- he was starting. Maybe he just wanted to be closer to home, maybe he wants to go back to defense, maybe he'll earn a scholarship down the line.

Seems like a no-brainer for UCLA. They got a highly-rated player who started as a freshman at a D1 program to walk on. If he plays well, great, he can even earn that scholarship. If he doesn't, it doesn't cost you anything and hopefully the kid earns a diploma. Win-win all around it seems to me.
