BALTIMORE (AP) -- A fierce defense led by Ray Lewis and Ed Reed came up with four turnovers to lead Baltimore to a 20-13 victory over the Houston Texans on Sunday, sending the Ravens into the AFC championship game.

The Ravens forced two turnovers in the first quarter and moved to a 17-3 lead, and interceptions by Lardarius Webb and Reed in the final eight minutes preserved the advantage.

Baltimore (13-4) will visit the New England Patriots on Sunday with the winner advancing to the Super Bowl.

The Ravens finished 9-0 at home.

One week earlier, in the first playoff game in Texans history, Houston (11-7) didn't give the ball away in a 31-10 home victory over Cincinnati.

In this one, rookie T.J. Yates was intercepted three times.
