Colin Kaepernick rested his throwing arm during Thursday’s short, non-padded 49ers practice.
A team spokesman said it was a “planned rest day” for the quarterback, who did not take part in any full practices in the spring because he was recovering from three surgeries. On Thursday, Kaepernick reverted to his spring routine: standing behind the other quarterbacks and mimicking their movements.
Kaepernick looked uncomfortable during Tuesday’s practice, at one point lying on the ground while a trainer stretched his right arm. He had surgery in November on his left shoulder.
He participated fully in Wednesday’s session at Kezar Stadium but was not efficient, completing 3 of 8 passes during team drills.
With Kaepernick resting, Blaine Gabbert took all of the first-team repetitions. He was 2 of 4, including an interception by safety Jaquiski Tartt on a pass that was tipped by safety Eric Reid.
Coach Chip Kelly said he will decide after Friday’s scrimmage against Houston who will start Sunday’s exhibition opener against the Texans.
Et cetera – Defensive end Arik Armstead (shoulder) was back in team drills after sitting out those sessions the past two days.
▪ Veteran tackle Erik Pears sat out practice. Pears, going into his 10th season, sometimes pulls double duty in practice, lining up at left tackle both with the first-team offense – to give Joe Staley a break – and with the second-team unit.
▪ John Parry and his officiating crew attended Thursday’s practice and will officiate the joint session with the Texans on Friday.
