Gary Hogeboom threw two touchdown passes late in the fourth quarter to rally the Dallas Cowboys to a 34-31 victory over the Houston Oilers last night in Irving, Tex.

Hogeboom and Butch Johnson teamed on an 18-yard scoring pass with 92 seconds to play.

Hogeboom, who replaced Danny White at the start of the fourth quarter, fell down, scrambled to his feet, and threw a two-yard touchdown pass to tight end Doug Cosbie to give Dallas a 27-24 lead with 3:05 to play.

Then Carl Roaches shocked the crowd of 54,363 by fielding the kickoff, breaking a tackle at the 10 and running 105 yards to give Houston the lead with 2:45 to go.

Hogeboom, who completed 11 of 16 passes for 119 yards, drove Dallas 62 yards in eight plays for its 13th victory in 17 games in the so-called "Texas Championship" series.

Hogeboom completed three straight passes before he found Cosbie alone in the end zone.

Houston trailed most of the game before going ahead, 24-20, with 9:36 left on Gifford Nielsen's five-yard pass to Mike McCloskey.

Houston's Earl Campbell scored on runs of one and 43 yards and gained 119 yards on 18 carries before he was taken out of the game early in the second half.
