"Ryan Grant wasn't sure if he turned back the clock.

He felt pretty good, however, about cleaning the Oakland Raiders' clocks.

Grant set the tone for the Green Bay Packers on the first play from scrimmage Sunday, bursting through a hole, making safety Michael Huff miss and then outrunning the rest of the Raiders' defense to the end zone.

His 47-yard touchdown run was nearly three times longer than his previous longest run this season - a 14-yarder against Chicago in Week 3 - and he helped revive a struggling ground game in the Packers' 46-16 victory.

"I don't know about turning back the clock," said Grant, who rushed for 1,253 yards in 2009 but then missed nearly all of 2010 with an ankle injury and went into the Raiders game with 92 carries for 316 yards (3.4 average) this season. "But I felt good. I felt fine."
