SANTA CLARA, Calif. — San Francisco cornerback Nate Clements will miss the 49ers’ minicamp this weekend with a case of pneumonia.

The 49ers’ $80 million cornerback missed organized team activities on Monday and Tuesday with the illness, and he won’t be re-evaluated until next week.
San Francisco lost fellow starting cornerback Walt Harris to a knee injury last month, and a knee injury also has kept veteran Shawntae Spencer out of the Niners’ offseason workouts. Newcomer Dre’ Bly and Tarell Brown lined up with the first-team defense for Tuesday’s practice, with kick returner Allen Rossum helping out.
