Saquon Barkley was carried off the field by trainers after a run early in the first quarter and the New York Giants fear he suffered a torn ACL.

The Giants said Barkley was undergoing X-rays on his knee. He will have more tests Monday, the team said.

One source said a torn ACL was "certainly within the realm."

Barkley was hurt as he ran toward the sideline and was being tackled by Chicago Bears safety Eddie Jackson. He grabbed at the knee as he was headed to the ground.
