San Francisco then defeated 49ers–Cowboys rivalry, the 1994 Dallas Cowboys season, 38–28, in the NFC Championship Game. Expected to be a close game, the 49ers converted 3 Dallas turnovers into 21 points in the first quarter. On the third play of the game, cornerback Eric Davis (American football) returned an interception from Cowboys quarterback Troy Aikman for a touchdown. Wide receiver Michael Irvin lost a fumble on Dallas next drive, setting up Youngs 29-yard touchdown pass to Watters. Then Cowboys returner Kevin Williams (wide receiver) lost a fumble on the ensuing kickoff, and it was recovered by kicker Doug Brien at Dallas 35-yard line. Several plays later, Floyd scored on a 1-yard touchdown run to give San Francisco a 21–0 lead less than 8 minutes into the game. With the score 24–14 in the closing minutes of the first half, Aikman threw 3 straight incompletions, and a short punt by the Cowboys set up Youngs 28-yard touchdown completion to Rice with 8 seconds remaining in the first half. The Cowboys eventually cut their deficit to 38–28 with a touchdown run by Emmitt Smith and Aikmans 10-yard touchdown pass to Irvin in the final period, but they were unable to score again. Although the Cowboys outgained the 49ers in total offensive yards (451–294), Aikman broke an NFC Championship Game record with 380 yards passing, and Irvin also broke an NFC Championship Game record with 192 receiving yards, Dallas was ultimately unable to overcome their first-quarter turnovers.
