SANTA CLARA – Even if quarterback Jimmy Garoppolo gains full medical clearance for 49ers training camp Friday, his supporting cast remains rife with health concerns.
Here are 10 players who could land on the active/physically-unable-to-perform list, where they could linger from only a day or into November, as is the case for rookies who go on the active/non-football-injury list:
1. Running back Jerick McKinnon: He hasn’t practiced since tearing his right knee’s anterior cruciate ligament a week before last season began.
2. Linebacker Kwon Alexander: Social-media posts of his recent workouts at 49ers HQ suggest he might be cleared to practice.
