NFC Championship, 1970: Dallas 17 San Francisco 10

Overall view of fans and field.

Game information
Although Dallas quarterback Craig Morton only completed 7 out of 22 passes for 101 yards, rookie halfback Duane Thomas rushed for 143 yards and caught two passes for 24 as Dallas converted two third quarter interceptions into 14 points to defeat the 49ers.

On the second drive of the game, 49ers quarterback John Brodie's 42-yard completion to Gene Washington at the Cowboys nine-yard line set up Bruce Gossett's 16-yard field goal to give the team a 3–0 lead, but only after Brodie misfired on a pass to fullback Ken Willard, who was open in the end zone. This would be the only score of the half for San Francisco. Dallas fared little better, with Mike Clark missing a field goal from 40 yards out, and later kicking a 21-yard field goal to tie the game, 3-3.

After each team punted once in the second half, San Francisco had the ball on their own 21-yard line. On the first play, Brodie was sacked by linebacker Dave Edwards for a seven-yard loss. Then on second down, Lee Roy Jordan intercepted Brodie's pass and returned it four yards to the 13, where Thomas scored a touchdown run for Dallas on the next play, breaking three tackles en route to the end zone. On San Francisco's next series, Mel Renfro picked off a pass from Brodie and returned it 19 yards to the Cowboys' 38-yard line, setting off a 62-yard scoring drive for his team. The key player on the drive was fullback Walt Garrison, who had a 12-yard carry, gained 24 yards on a screen pass, and finished it off with a five-yard touchdown catch from Morton to give the Cowboys a 17–3 lead.

San Francisco responded with an eight-play, 72-yard drive to score on Brodie's 26-yard touchdown pass to tight end Dick Witcher and cut the score to 17–10 going into the fourth quarter, but they were shut out for the rest of the game. They nearly got a big scoring chance when Thomas fumbled the ball, but receiver Reggie Rucker recovered it, allowing Dallas to keep possession and take a lot of time off the clock with a drive to the 49ers 17-yard line. Clark missed a field goal attempt from there, giving San Francisco a chance to drive for the tying touchdown, but the farthest they could make it was to the Dallas 39, and after Renfro broke up a third down pass, Gossett missed a field goal from 47 yards out, and 49ers would not threaten to score again.

This was the 49ers' first playoff game at home since 1957 and the team's last home game to be played at Kezar Stadium. Johnny Mathis sang the national anthem, and Tony Bennett performed his signature song "I Left My Heart in San Francisco" at halftime.

This was the first postseason meeting between the Cowboys and 49ers.
