Quarterbacks Adrian Martinez and Michael Penix had been committed to Tennessee since last spring.

They announced their decommitments on Wednesday within two hours of each other.

Martinez wrote on Twitter that he's now committed to Nebraska. Penix hasn't announced his new destination but wrote on Twitter that it won't be UT.

"After conversations with the new staff it seems that's not the place I'm being wanted," Penix wrote.

Later, Martinez posted a graphic announcing his pledge to the Huskers, who gained momentum in the quest for his services after their hire of Scott Frost, the former Nebraska quarterback who led Central Florida to a 13-0 record this season.

Martinez visited Nebraska last weekend.

Martinez, from Clovis West High School in Fresno, Calif., is rated a four-star dual-threat QB by 247 Sports. He'd been committed to UT since May 12. New Vols coach Jeremy Pruitt and offensive coordinator Tyson Helton visited him in California on Monday.

Penix, rated a three-star pro-style QB from Tampa Bay Tech High School in Florida, received an offer from Florida State on Sunday. He's gone on visits to South Florida and Indiana, from which he also has offers. He'd been committed to UT since April 22.

Following the quarterbacks' decommitments, the Vols have 11 players pledged to their 2018 class. That contingent now includes no QBs.

The early signing period begins Dec. 20.

The Vols are set to return three scholarship quarterbacks: Jarrett Guarantano, Quinten Dormady and Will McBride. Each started at least one game in 2017. But adding a prospect in the 2018 class would be welcome insurance, especially in case one of the players set to return transfers.

The Vols picked up a recommitment from four-star wide receiver Alontae Taylor earlier Wednesday. He became the first player to commit to UT since Pruitt was hired on Dec. 7.
