Answer based on context:

Looking to improve to 5-0 on the road, the Cardinals went to their former home for a Week 11 duel against divisional rival St. Louis Rams. The Rams would score first, on a Josh Brown field goal following a fumble by Chris "Beanie" Wells.  However, the Cardinals would score the next 21 points, as Kurt Warner connected with Anquan Boldin for a touchdown at the end of the first quarter, followed by a Warner to Larry Fitzgerald touchdown and a Beanie Wells rushing touchdown in the second quarter. During the second touchdown drive of the second quarter, Warner was hit hard by St. Louis safety O.J. Atogwe, with his head hitting the turf as he went down.  Warner played the remaining six plays of the drive, but was replaced for the remainder of the game by backup quarterback Matt Leinart.  Leinart struggled with a more conservative game throughout the second half, and the Cardinals did not score for the remainder of the game.  St. Louis attempted to rally; however, they were only able to muster a second Josh Brown field goal and a Steven Jackson touchdown. With the win, the Cardinals improved to 7-3; however, Warner's status remained questionable for the next week's game against the Tennessee Titans.

How many touchdown passes did Kurt Warner throw in the first quarter?
