SANTA CLARA — Brock Purdy was excused Friday from the 49ers’ third practice of training camp because of personal reasons that are not expected to prompt a multi-day absence.
Mac Jones and Tanner Mordecai were the 49ers’ only quarterbacks for a practice that preceded Saturday’s day off. Jones opened as the first-string quarterback and completed his first pass of team drills to Jauan Jennings.
Purdy practiced each of the previous two days, and he had a strong showing Thursday with just one incompletion after having back-to-back passes intercepted early in Wednesday’s first practice of camp.
Purdy’s absence Friday is not injury-related, according to a team spokesman. In May, he signed a team-record contract extension (five years, $265 million) as he heads into his fourth season.
Rookie Kurtis Rourke is on the Non-Football-Injury list as he rehabilitates from an anterior cruciate ligament repair he underwent in January.
