Ricky Pearsall already has returned to the 49ers’ facility after he was shot in the chest on Saturday in San Francisco. The rookie wide receiver was released from Zuckerberg San Francisco General Hospital on Sunday, less than one day after he was shot in an armed robbery attempt near Union Square. And less than two days later, Pearsall was around teammates again on Monday at the team’s facility in Santa Clara, 49ers radio color analyst Tim Ryan revealed Tuesday morning on KNBR 680’s “Murph & Markus.”
