Philadelphia Eagles quarterback Nick Foles will undergo further testing Friday on a strained shoulder, according to ESPN's Adam Schefter.

He suffered the injury early in the second quarter of Thursday's preseason game against the New England Patriots on a strip sack by defensive end Adrian Clayborn. The loose ball was recovered by Ja'Whaun Bentley and returned for a 54-yard touchdown.

Foles told reporters after the game that he feels "pretty good," Schefter adds.

Strip sack! Recovery!

Concern for Foles is heightened as this injury comes just two days after starting quarterback Carson Wentz indicated he may not be ready for Week 1 as he recovers from the torn ACL that ended his 2017 season.
