49ers safety Eric Reid sustained a torn biceps in the second half of the 30-17 loss to the Patriots, according to NFL media. It’s likely a season-ending injury.

The news comes in addition to defensive back Jimmie Ward sustaining a concussion.

Reid tied for the team lead with seven tackles Sunday against New England, who amassed 444 yards of offense on the back of Tom Brady, who threw four touchdown passes.

With Reid likely done for the year, the 49ers remaining healthy safeties are Antoine Bethea, Jaquiski Tartt, Marcus Cromartie and Dontae Johnson, who has played both safety and cornerback this season.

When Ward is healthy, he is also a potential option at safety. He played safety at Northern Illinois, but has not yet in since the 49ers drafted in the first round in 2014.
