Steelers kicker Jeff Reed booted a 47 yard field goal with 4 seconds remaining to give the Steelers a 12-10 victory over the Minnestoa Vikings in the third preseason contest of the season.

The Steelers first string defense limited Minnesota’s star running back Adrian Peterson to 21 yards on 12 carries, although it allowed its fourth touchdown of the preseason.

Ben Roethlisberger completed 10 of 17 passes for 65 yards, although the pass blocking of the offensive line was poor, putting Big Ben under constant pressure. The Steelers play their final preseaon game next Thursday against the Carolina Panthers.
