Examine all the grassy knoll footage you want. Spin every alternative theory you can muster. But Nick Foles practiced Monday, and barring something catastrophic, he is going to be the Eagles’ backup quarterback when the regular season opens Sept. 10 at Washington.
According to a source with knowledge of the situation, early in training camp Foles was found to have a flexor tendon strain and inflammation around a nerve in his throwing elbow. The ulnar collateral ligament, which is the part of the elbow that merits Tommy John surgery when it has to be fixed, was fine.
Foles grappled with this same problem last year in Kansas City, the source said, so the Eagles’ medical staff gave him a lot of rest during training camp and the preseason, hoping the soreness would go away.
