A green light appeared on the five-time Super Bowl champion multiple times during the Patriots' 37-31 overtime win against the Kansas City Chiefs on Sunday at Arrowhead Stadium in Kansas City.
A photographer from KMBC recorded video of the green dot flickering around Brady's upper body and face.
Brady completed 30-of-46 passes for 348 yards, one score and two interceptions in the win. Neither team commented on the incident during postgame interviews.
The Patriots battle the Los Angeles Rams in Super Bowl LIII at 6:30 p.m. on Sunday, Feb. 3 at Mercedes-Benz Stadium in Atlanta.
