In this photo taken Tuesday, Jan. 3, 2012, Cincinnati Bengals quarterback Andy Dalton throws a pass during NFL practice in Cincinnati, for this Saturday's NFL football playoff game in Houston. Dalton is 3-0 at Reliant Stadium in Houston having played there as a high school and college quarterback. He goes back there on Saturday for a wil-card playoff game against his hometown Texans.

CINCINNATI — Bengals quarterback Andy Dalton has returned to practice after missing a day because of the flu.

The rookie said his illness came on suddenly and he went to a hospital for treatment to recover quickly. He was eating again on Thursday and watched film of what he'd missed in practice the previous day, trying to catch up.

The weather was much nicer for practice — 40 degrees when the Bengals took the field at Paul Brown Stadium, a vast improvement over earlier in the week when Dalton got sick. The Bengals don't have a covered practice field.

Dalton will return to his hometown when the Bengals play the Texans in Houston on Saturday, trying to win a playoff game for the first time since the 1990 season.
