Colt McCoy took his place as the Giants held on for the win, leaving them tied for first place in the NFC East with the Washington Football Team. The Giants (4-7) have already beat Washington twice this season.
Jones was injured at the end of a 7-yard run. He briefly reached for the back of his right leg while on the ground, but remained in the game. Two plays later, Jones could hardly drop back and made an awkward third-down throw while limping. He went to the ground and again grabbed at the back of his leg, before being taken off the field and being sent to the medical tent for treatment.
Jones returned the following drive for two plays. After limping onto the field, he threw one pass before being removed from the game. He was unable to drive the ball with the leg clearly a problem.
The Giants were tied 10-10 with the Bengals when Jones left the contest. They settled for a field goal several plays after he exited.
Jones was playing some of the best football of his career prior to the injury. He was 16-of-26 passing for 213 yards before hurting his leg early in the third quarter. He would have done even more damage had it not been for a dropped deep pass by wide receiver Darius Slayton and a costly fumble by tight end Evan Engram in the first half.
Jones entered Sunday having completed 62.5% of his passes this season with eight touchdowns and nine interceptions. But he hadn't committed a turnover in consecutive games for the first time in his career entering the matchup with the Bengals.
