Foles was optimistic about the injury after the game, saying he would undergo further tests Friday after meeting with team trainers. "I feel really good about it," Foles said.
Philadelphia announced the injury as a shoulder strain and Foles didn't return. Ja'Whaun Bentley scored a touchdown after he scooped up the loose ball caused by Clayborn's strip sack.
With Carson Wentz being eased back from reconstructive knee surgery, Foles started the team's second preseason game, completing just three of nine passes for 44 yards. Although he was under heavy pressure from New England's pass rush, he didn't do himself any favors with scattershot accuracy.
Foles was rusty from the opening whistle, sailing his first pass out of bounds. His next few throws were high, behind and over his targets. All things considered, it was a deflating outing for Philadelphia's trusty backup.
