Kaelon Black was held to a limited practice Thursday by a groin injury, according to a report from cbssports.com that cited Matt Maiocco of NBC Sports Bay Area. Black could not complete the full session with the San Francisco 49ers.
The injury had not appeared on San Francisco's Wednesday injury report. No details about its severity were provided in the report.
The 49ers are expected to provide another update Friday when they release their final injury report before Sunday's game against the Dolphins. That report is expected to indicate whether Black remains limited ahead of the matchup.
