UCLA quarterback Josh Rosen was selected by the Arizona Cardinals with the 10th pick in the NFL draft.
The Cardinals traded up five spots to select Rosen.
Rosen was the fourth quarterback chosen. The Cleveland Browns took Heisman Trophy winner Baker Mayfield of Oklahoma first, the New York Jets selected USC quarterback Sam Darnold with the third pick, and the Buffalo Bills traded up seven spots to select Josh Allen with the fifth pick.
"I just want to put some pads on get to work," Rosen said.
Rosen is the first Bruins quarterback drafted since the Green Bay Packers selected Brett Hundley in the fifth round in 2015. He is the first UCLA quarterback selected in the first round since Cade McNown was selected 12th by the Chicago Bears in 1999. Troy Aikman was selected first overall by the Dallas Cowboys in 1989, Tommy Maddox 25th by the Denver Broncos in 1992.
Rosen, 6-feet, 4 inches and 226 pounds, was a three-year starter for the Bruins.
He completed 60.9 percent of his passes for 9.340 yards and 59 touchdowns, with 26 interceptions.
Rosen, who played at Bellflower St. John Bosco High, burst onto the college scene in the first game of the 2015 season, when he completed 28 of 35 passes for 351 yards and three touchdowns.
Rosen suffered a shoulder injury during the 2016 season and underwent surgery.
He played in 11 games last season, passing for 26 touchdowns, with 10 interceptions.
