NFL Scores Week 6: 49ers Come Back, Win 25-19 Thriller Against Lions

San Francisco came back to beat Detroit behind Alex Smith. But Jim Harbaugh's demonstrative celebration didn't sit well with Jim Schwartz.

Oct 16, 2011 - Alex Smith's finest moment as the 49ers' franchise quarterback may have come in San Francisco's 25-19 win over Detroit on Sunday. But chances are that Jim Schwartz' postgame altercation with Jim Harbaugh will be the talk of the NFL pundit class for the next few days.

Smith threw for just 125 yards, but led the Niners down the field late and found Delanie Walker for the game-winning touchdown pass with less than two minutes to go in the fourth quarter. Frank Gore helped the Niners, too, with 141 rushing yards and a touchdown.

But Schwartz took exception to what he saw as Harbaugh's excessive celebration, and went after the first-year San Francisco coach after a brusque postgame handshake. Schwartz and Harbaugh had to be separated, but it appeared that Schwartz was the aggressor throughout.

With the win, the Niners move to 5-1 for the first time since 1998, while the Lions fall from the ranks of the unbeatens, dropping to 5-1 with the loss and leaving NFC North rival Green Bay as the only team with a blemish-free record.

Matthew Stafford threw for 293 yards and two touchdowns in the losing effort, and Calvin Johnson, who had seven catches for 113 yards, failed to catch a touchdown pass for the first time in the 2011 season. The Lions didn't score after Stafford found Nate Burleson for a go-ahead touchdown early in the fourth quarter.
