Write an article that answers the following question: How many points were the Browns ahead going into the half?
The Browns opened their season at home against the Minnesota Vikings trying to improve on their 4-12 record from last season. After trading field goals in the first quarter, RB Adrian Peterson scored the first touchdown of the game, giving Minnesota a 10-3 lead. But K Phil Dawson kicked his second field goal and WR Josh Cribbs returned a punt for a touchdown and the Browns took a 13-10 lead into halftime. However, the second half was controlled completely by the Vikings, with QB Brett Favre connecting with WR Percy Harvin for Favre's first touchdown pass as a Viking. In the 4th quarter, QB Brady Quinn completed a touchdown pass to TE Robert Royal, the first touchdown by Cleveland's offense since the 4th quarter of Week 11 in 2008, ending a span of 416 offensive plays without a touchdown.
