Rookie quarterback Tim Tebow made his first preseason appearance Sunday night, making it into the end zone on the final play of a 33-24 loss to the Cincinnati Bengals. Tebow went 8 of 13 for 105 yards in the second half, with most of the completions and yards coming on the final drive against a soft defense. That one ended with Tebow scrambling 7 yards for a touchdown, running over safety Kyries Hebert to score. Kyle Orton was impressive in his preseason debut, throwing two touchdown passes in three series and reminding Broncos fans that he's the one running the offense if not selling the most jerseys. 49ers 37, Colts 17: At Indianapolis, David Carr threw one touchdown pass as San Francisco scored 34 straight points to pull away for a preseason win.
