Houston, TX -- (Sports Network) - Kris Brown kicked a game-winning, 25-yard field goal as time expired to lead the Houston Texans to a 19-16 win over the Denver Broncos in the preseason opener for both teams.

Brown went 4-for-4 on his field goal attempts, including a 52-yarder, while Sage Rosenfels went 10-for-15 with 137 yards and a score for the Texans (1-0), who are coming off an 8-8 season, their most successful in franchise history.

Matt Prater hit three of his four field goal attempts while Jay Cutler went 8- for-10 with 59 yards and had a 15-yard touchdown run for the Broncos (0-1), who are looking to bounce back from a disappointing 7-9 season.

A pair of field goals from Prater tied the game in the fourth quarter, with the last one coming with under six minutes to play to make it a 16-16 game.

Houston, though, drove down the field and Brown split the uprights as time expired for the win.

After a 23-yard field goal from Brown, Cutler took the ball into the end zone himself and the Broncos took a 7-3 lead into the second quarter.

Brown hit a 52-yarder a bit over three minutes into the second and Rosenfels hooked up with David Anderson on a 16-yard score to give Houston a 13-7 lead heading into the locker room.

Brown and Prater exchanged field goals in the third quarter and the Texans led, 16-10, to start the final stanza.

A scary moment happened in the first quarter as Denver linebacker Louis Green left the field on a stretcher with a neck injury and a concussion.

He collided with teammate D.J. Williams as the two converged on a tackle of Texans tight end Owen Daniels, who caught a short pass on the play.

He laid motionless on the field for several minutes as medical staff rushed to check on him. Green was strapped to the stretcher and was moving his fingers and hands when he was rolled off the field.

Green was taken to a hospital for further evaluation and was later released. He will accompany the team on its flight back to Denver.
