Foster, in his fourth year out of UCLA, rushed for 131 yards last Sunday as the Panthers dumped Atlanta, 24-6, to move a step closer to the NFC South division title. It was the first time a Carolina running back topped the 100-yard mark this season.
Foster, who tied a league record with the Eagles' Brian Westbrook with six receptions of at least 20 yards in a season, was joined by Seattle cornerback Andre Dyson (defense) and punter Jeff Feagles of the New York Giants (special teams).
Dyson had both an interception return and a fumble return for touchdowns in the Seahawks' 42-0 win over Philadelphia and was the second defensive player in team history with two touchdowns in one game.
Feagles averaged 44.7 yards on six punts in the Giants' 17-10 win over Dallas.
