ORCHARD PARK, N.Y. -- Buffalo Bills tight end Charles Clay underwent left knee surgery Monday and will be out multiple weeks, coach Sean McDermott said.
Pro Football Talk reported Clay tore his meniscus and sprained his MCL. McDermott said Monday he had yet to speak to doctors about the injury and was not sure if it would be season-ending.
"Next man up, that's what we do," McDermott said. "That's what happens in the league. Sometimes this happens. We've gotten hit a little bit by the injury bug."
Clay leads the Bills this season with 258 yards on 20 catches.
