Chip Kelly’s first UCLA recruiting class continues to grow more than a week after National Signing Day.

UCLA announced the signing of quarterback KJ Carta-Samuels on Thursday, adding the graduate transfer from Washington who backed up UW’s Jake Browning for the past three seasons.

The 6-foot-1, 216-pound quarterback told CBS Sports he planned to transfer to UCLA in January. He will be immediately available for his final year of eligibility as he is expected to graduate from UW in March and join the Bruins in time for spring practice, when he will start competing for the starting quarterback position.

Along with true freshman Dorian Thompson-Robinson, who signed his National Letter of Intent on Jan. 7 with 26 other recruits, UCLA has returning backups Devon Modster and Matt Lynch. The Bruins also have redshirt freshman Austin Burton, a former three-star recruit from Florida.

Modster started two games last year, including UCLA’s bowl game, in which he threw for 295 yards and two touchdowns against Kansas State.

Carta-Samuels played in 25 games for the Huskies with one start, completing 27 of 47 passes for 310 yards, three touchdowns and one interception. The Bay Area native was a U.S. Army All-American out of Bellarmine College Prep in San Jose, where he was the No. 10 pro-style quarterback prospect in the country for the 2014 class, according to Rivals.com.

Carta-Samuels will face his former team on Oct. 6 when the Bruins host Washington at the Rose Bowl.

The 27-player recruiting class Kelly signed last week was ranked fourth in the Pac-12 and 18th nationally, according to 247 Sports’ Composite Rankings. It was already the largest of any school in the conference.
