Houston and Green Bay clinched division titles with victories over their closest pursuers, and there is a three-way tie for the lead in the NFC East as a result of Sunday’s Week 15 games in the National Football League.

The Texans also clinched a first round bye when New England lost to San Francisco, 41-34, on Sunday night. There were no Andrew Luck late-game heroics as Houston defeated the Indianapolis Colts, 29-17, and took the AFC South title. Green Bay wrapped up the NFC North by defeating the arch-rival Bears, 21-13, in Chicago.

The defending Super Bowl champion New York Giants were embarrassed, 34-0, by the Falcons in Atlanta to fall to 8-6. Meanwhile, Washington and Dallas won their games to pull into a first-place tie with the Giants.

Game of the day

49ers 41, Patriots 34

The scoop: The 49ers and Colin Kaepernick (four touchdown passes) shredded the Patriots early, then took advantage of New England miscues to build a 31-3 lead but needed a late Kaepernick-to-Michael Crabtree pass for 38 yards to pull out the victory. Kaepernick began with a 24-yard TD pass to ex-Patriot Randy Moss. New England scored 28 unanswered points to tie the game with 6:43 left. The Niners needed only 18 seconds to reclaim the lead.

Why the 49ers won: Their pass rush overpowered New England’s front and they outmuscled the Patriots across the board.
