Whitner and Lacy go helmet-to-helmet (GIF)

The San Francisco 49ers and Green Bay Packers are within a field goal at halftime from Lambeau Field.

San Francisco settled for two first quarter Phil Dawson field goals after failing to punch it in the end zone with two golden opportunities.

Green Bay took the lead, 7-6, midway through the second quarter after a 14-play, 70-yard drive and a Jordy Nelson 5-yard touchdown reception on a pass from Aaron Rodgers.

San Francisco took their next drive 5 plays and 68 yards, highlighted by a 42-yard Colin Kaepernick run and a 10-yard Frank Gore touchdown scamper to put the 49ers ahead 13-7.

Green Bay took their subsequent drive right back down the field – this time a 9-play, 59-yard affair – and ended up with a 34-yard Mason Crosby field goal to bring the score to 13-10 at the midway point of this Wild Card playoff game.

There have been plenty of hard hits from both teams – on offense and defense – in the subzero temperatures in Green Bay.

On the Packers final field goal drive, Packers’ running back Eddie Lacy and 49ers’ safety Donte Whitner met head to head – literally – at the two minute mark of the second quarter.

Check out the helmet clash below:

The second half is underway as San Francisco takes over from the 18-yard line.  Expect the more hits similar to this one as the game rolls on.  That has got to hurt in these temps.
