Kyle Boller walked onto the field with 64 seconds left, no timeouts and his Baltimore Ravens down by two points.

Starting at his own 13 yard-line, the oft-criticized quarterback faced the prospect of moving the ball behind a makeshift offensive line. Fortunately, he was operating against the Houston Texans.

Boller came through, and Matt Stover kicked a 38-yard field goal with six seconds remaining to give Baltimore a 16-15 win.

A game filled with blunders, fumbles and penalties ended in familiar fashion for the Texans, who let a seemingly certain win get away for the second straight week.

Boller completed a 24-yard pass to Todd Heap on third down, then hit rookie Mark Clayton with an 11-yarder. Two plays later, a 35-yard completion to Clayton got the Ravens into field goal position.

"It excites me as a veteran here to see that we didn't give up and we did enough to win the game," said Stover, who has kicked 11 game-winners over a 15-year career.

Matt Stover kicks the game-winning field goal, the 11th of his career, as Dave Zastudil holds. Baltimore's winning drive covered 67 yards in 56 seconds.
