Jones was tackled at the goal line by two Cowboys players in the second quarter. He was examined on the field by Giants trainers and carted back to the locker room.
Jones missed two games last season because of hamstring and ankle injuries. The then-second-year quarterback sat out New York's 17-12 win over the Seattle Seahawks with a strained hamstring he originally suffered the previous week against the Cincinnati Bengals.
The Giants signed veteran Mike Glennon in the offseason to serve as Jones' backup. Glennon started five games for the Jacksonville Jaguars in 2020, throwing for 1,072 yards with seven touchdowns and five interceptions.
Jones has a lot riding on this season. The Giants can exercise the fifth-year option on his rookie contract next offseason. If he performs well this year, that option will be a no-brainer for the organization.
Through four games, the results have been mixed for Jones and bad for the Giants. He has thrown for 1,184 yards, run for 188 yards and accounted for six touchdowns.
