Working overtime paid off for Minnesota and Houston this weekend.
Seattle avoided the extra session and made it a wild-card bonanza, with three of the four road teams winning.
One day after the Texans rallied from a 16-0 deficit to beat Buffalo 22-19 in an AFC wild-card game, the Vikings stunned New Orleans 26-20 on Sunday.
Then fifth-seeded Seattle edged undermanned Philadelphia 17-9.
The Texans (11-6) will travel to Kansas City (12-4) next Sunday in the divisional round. Tennessee (10-7), which ended New England's run of three straight Super Bowl appearances with its victory Saturday at Foxboro, gets a trip to Baltimore (14-2) next Saturday night.
