The Eagles had a 13-10 lead with three seconds remaining when Oakland quarterback Derek Carr accepted a snap while his team was at its own 36-yard line.
Carr completed a short pass to wide receiver Amari Cooper, who then pitched the ball to running back Jalen Richard. Richard missed Carr with his attempted lateral, however, and Philadelphia defensive end Derek Barnett returned the fumble 23 yards for the score.
Rather than kick the extra point with no time remaining, Eagles quarterback Nick Foles took a knee to cement the 19-10 victory.
Per OddsShark, multiple sportsbooks listed the Raiders as 10-point underdogs ahead of Monday's kickoff, meaning Barnett's touchdown and Philadelphia's decision to sit on the nine-point advantage resulted in either a happy or unhappy holiday for those who bet on the contest.
