Juanyeh Thomas: Everything you need to know

The Colts signed Thomas (migraine) to a one-year contract Friday, James Boyd of The Athletic reports. Thomas dealt with migraines for most of last season and was shut down in December after initially being placed on the reserve/non-football illness list in November. Thomas has appeared in 36 career regular-season contests and will serve in a depth role for the Colts.

Thomas (migraine) won't return this season, head coach Brian Schottenheimer revealed Friday, Clarence Hill Jr. of alldlls.com reports. Thomas has been on the reserve/non-football illness list since Nov. 11. The 25-year-old safety will likely need to resolve his migraine issues prior to signing with any NFL team after he becomes an unrestricted free agent in the offseason.

The Cowboys placed Thomas (migraines) on the reserve/non-football illness list Tuesday, Joe Hoyt of The Dallas Morning News reports. Thomas has missed two of the past three games due to migraines, and he'll now miss at least the next four contests. Thomas had started each of the last three games in which he appeared, logging at least 91 percent of the defensive snaps in all of those, so it's a significant loss to the Dallas defense. The Cowboys don't have a single truly healthy safety on the roster, as all five are dealing with some sort of injury.
