Santos missed much of training camp and the preseason with a groin injury but returned in time for the start of the regular season.
The Los Angeles Chargers were penalized for roughing the kicker against Chiefs and Santos on his 51-yard field goal that went wide left in Sunday's game. But Santos was able to finish the game. He made a 34-yard field goal later on the same drive and also went on to kick off twice more and make a point after touchdown.
Butker was the Panthers' seventh-round draft pick from Georgia Tech. He made both of his field goal attempts in the preseason, each from beyond 40 yards. He was also 4-for-4 on extra points.
Santos, 25, is 3-for-3 in field goal attempts this season and has made all 12 of his extra-point attempts.
