’49ers WR Emmanuel Sanders: It’s well-known the Bills will be in the market for a wide receiver (or two). Sanders joined the 49ers in a midseason trade with the Denver Broncos and was highly productive, making 36 catches for 502 yards and three touchdowns in nine games with San Francisco. He had three catches for 38 yards against the Chiefs. Sanders turns 33 next month, so he would be a shorter-term addition.’
