The injury took place late in the second quarter. Giants defensive end Kayvon Thibodeaux rushed Foles untouched and sacked him on his blindside. The tackle drove Foles' upper body into the turf. Foles then convulsed on the field as Thibodeaux celebrated the sack.
Athletic trainers tended to Foles as he remained on his back. He eventually walked to the sideline on his own before a cart drove him off the field. The Colts announced at halftime that Foles was ruled out with a rib injury.
Thibodeaux addresses celebration: 'I hope he's all right'
Thibodeaux took heat for celebrating while Foles was injured. He told reporters after the game that he wasn't aware of the injury until he stood up after making mock snow angels.
"When I did realize that he was hurt, that’s when we started getting up," Thibodeaux said, per ESPN's Kimberley A. Martin. "When you’re doing a celebration, you’re not looking to see who’s doing what. But I hope he gets well and I hope he’s all right.”
Head coach Jeff Saturday told reporters after the game that Foles was in a "ton of pain," but the Colts didn't offer a prognosis after their initial designation of a rib injury.
Foles took over as the Colts' starting quarterback in Week 16 after Indianapolis benched Matt Ryan for the second time this season. Ehlinger entered Sunday having completed 32 of 52 pass attempts for 304 yards with an interception and no touchdowns in two previous appearances this season. He completed 9 of 14 passes for 60 yards and a touchdown in the second half on Sunday.
