Harbaugh: You don't throw for 400 yards without great protection
SAN FRANCISCO -- The 49ers got another play they should not have received in the second quarter, and they took full advantage.
Referee Bill Leavy admitted an officiating error provided the 49ers with another third-down play, which they turned into a touchdown.
The 49ers went on to a season-opening 34-28 victory over the Green Bay Packers at Candlestick Park.
Packers linebacker Clay Matthews was penalized for a hit out of bounds on 49ers quarterback Colin Kaepernick, who ran out of bounds 2 yards short of the first down on a third-and-6 play at the Green Bay 10.
Left tackle Joe Staley was penalized for unsportsmanlike conduct after running over to confront Matthews. Leavy incorrectly ruled the offsetting penalties negated the third-down play.
"On the play where the quarterback went out of bounds and was hit late out of bounds and there was the subsequent hit by a San Francisco player, the down should've counted on it," Leavy told a pool reporter.
"The penalties should have offset at the spot where the runner went out of bounds and it would've been fourth down."
Instead of settling for a 23-yard field-goal attempt, the 49ers scored on Kaepernick's 10-yard touchdown pass to Anquan Boldin.
"It was dumb," Staley said. "It was somehthing I wish I hadn`t done."
When told the official incorrectly ruled a replay of third down, Staley said, "Well, they called it third down. Good. All the more reason I should've kept my cool."
