Thomas finished with three tackles (two solo), including 1.5 sacks and a tackle for a loss, in Sunday's 29-9 win over the Bears.
The linebacker also played on 35.0 percent of the defensive snaps as he continues to share time with Julian Okwara as Arizona's third linebacker. Thomas and Okwara were the next men up after Dennis Gardeck suffered a season-ending ACL injury in the Cardinals' Week 7 win over the Chargers.
