Peyton Manning fired two touchdown passes to Eric Decker Sunday, but the San Francisco 49ers rallied for a 29-24 pre-season win over Denver. Manning found the end zone for the first time since joining the Broncos in the off-season after being released by Indianapolis, connecting with his wide receiver on scoring strikes of 10 and 5 yards in the first quarter. He also led the Broncos on an opening drive that resulted in a 53-yard Matt Prater field goal. Decker finished with four catches for 38 yards. San Francisco quarterback Alex Smith was 5-of-7 for 69 yards, including a 44-yard touchdown toss to Vernon Davis. Rock Cartwright\'s 27-yard run with 3 minutes left in the game set up a go-ahead, 49-yard field goal by David Akers for the 49ers.
