49ers, Lions Head Coaches Botch Post-Game Handshake: After the San Francisco 49ers knocked off the previously undefeated Detroit Lions 25-19 at their house, the head coaches nearly ignited a post-game brawl over their handshake. "I shook his hand too hard," said 49ers coach Jim Harbaugh, whose team climbed to 5-1. Lions coach Jim Schwartz claimed Harbaugh yelled an obscenity at him. "There’s a protocol that goes with this league," he said. In other week 6 games, Tampa laid out New Orleans and coach Sean Peyton, New England downed Dallas with a last-minute touchdown and Philadelphia won a game.
