The Seattle Seahawks and Arizona Cardinals stumbled to a 6-6 tie Sunday night in the desert, the fourth deadlock since the NFL instituted new overtime rules prior to the 2012-13 season. Second-string quarterback Matt Flynn helped the Packers rally from a 23-7 deficit in the fourth quarter, and Mason Crosby put the them ahead 26-23 with a 20-yard field goal 4 1/2 minutes into OT. The visiting Vikings rallied for a 12-play drive that ended with Blair Walsh's 35-yard field goal with 3:54 left. Cincinnati's Andy Dalton only missed on one pass in overtime — a sack-saving throwaway — and Cam Newton engineered a 12-play scoring drive in OT for visiting Carolina, but this one still ended in a tie.
