SANTA CLARA, Calif. — The San Francisco 49ers added two more players to their injured reserve list Saturday, one of which leaves them particularly thin at cornerback.
Nickelback K’Waun Williams is headed to injured reserve because of a sprained knee, which means he must miss at least the next three games. Defensive end Ezekiel Ansah (torn biceps) has also officially been added to injured reserve and will miss the rest of the season.
Williams joins starting cornerback Richard Sherman (calf) on IR and with Emmanuel Moseley out this week as he continues to deal with a concussion, the Niners will be without their top three cornerbacks for Sunday’s game against the Miami Dolphins.
All of that left the 49ers with no choice but to elevate a pair of cornerbacks from the practice squad for this week. Jamar Taylor, who will step into Williams’ spot in the slot, has been promoted from the practice squad to fill one of the open roster spots
