DeAndrew White

Defense won Thursday's 49ers practice as Blaine Gabbert (4 of 13) and Colin Kaepernick (6 of 14) struggled in 11-on-11 drills.

Each quarterback did get the ball in the end zone, Kaepernick doing so early on with a 50-yard strike to Torrey Smith. Gabbert's best pass might have been a touchdown throw to DeAndrew White, who had his best day of camp.

Kaepernick went 0 for 4 during a seven-on-seven period, capped by Jimmie Ward's interception. Offensive coordinator Curtis Modkins said before practice that Kaepernick had done well in what remains an early competition.
