SANTA CLARA, Calif. (AP) — San Francisco 49ers wide receiver and return man Kyle Williams says he will miss the rest of the season with a torn ligament in his left knee sustained in Sunday’s win at New Orleans.

Williams posted on his Twitter account Monday that he has a torn anterior cruciate ligament in his left knee. Surgery would be the likely next step.

Coach Jim Harbaugh provided no updates Monday.

Williams and running back Kendall Hunter both were hurt on the same play during the second half of Sunday’s 31-21 win over the Saints.

Both were helped off the field and were soon after taken by cart to the locker room. They were injured on a running play in which Hunter carried the ball for a 2-yard gain late in the third quarter.
