Still only 29 years old, Thompson played as recently as 2021. A 2016 third-round pick of the Giants, he spent 2019-21 in Dallas, overlapping with coach Mike McCarthy. 

A former third-round draft pick for the Giants, Thompson spent the past four seasons bouncing on and off the Cowboys' active roster. He's logged 28 starts in six NFL seasons. Thompson, 29, would probably be a rotational player in the Indianapolis secondary if he signs with the Colts. 

The organization didn't announce whether Thompson tested positive or was simply a close contact, but it's far too late into the week for him to turn around for Sunday. Dallas will also be missing LB Leighton Vander Esch and S Xavier Woods against the Giants.

Dallas lost a large chunk of the defense, including CB Byron Jones, but they'll keep their 45-tackle safety for two more seasons with this re-signing. As just alluded to, Thompson will have a lot more responsibility moving forward as a safety in addition to any special teams duties he serves. Thompson will be turning 27 within the first month of the 2020 NFL season.
