The muscle spasms are unrelated to the elbow issue Foles dealt with early last season.
Here are other injuries we're tracking in camps this Tuesday:
- Carolina Panthers guard Amini Silatolu will undergo surgery Friday to repair a torn meniscus in his left knee, the team announced. His return to the field will be evaluated on a week-to-week basis.
In addition, guard J.R. Sweezy is dealing with a sprained ankle on the same leg he broke during his time with the Tampa Bay Buccaneers, Carroll said.
- Kansas City Chiefs safety Daniel Sorensen does not have a torn ACL, but he could miss the early part of regular season with the leg injury, a source told NFL.com's Herbie Teope.
