New backup quarterback Kellen Clemens threw a 70-yard touchdown pass to Dontrelle Inman midway through the third quarter and the San Diego Chargers beat the Dallas Cowboys 27-7 Thursday night in an exhibition opener.
Inman, who played in the CFL the last two seasons, beat single coverage down the right sideline and was gone to give San Diego a 17-7 lead.
Meanwhile, Chargers rookie running back Branden Oliver put his name on the map with a seven carry, 64-yard performance, including a sizzling 17-yard touchdown run in the second quarter that tied the game at 7.
San Diego's quarterbacks were equally impressive, at one point combining for a perfect 12-12 passing. They finished 14-16 for 243 yards and zero interceptions. Starting quarterback Philip Rivers played only one series, finishing 4-4 for 61 yards.
Clemens made his Chargers debut after signing as a free agent in March and replacing Charlie Whitehurst as backup to Rivers. Clemens spent the last two seasons with the St. Louis Rams as a backup to starter Sam Bradford. He started the last nine games after Bradford went down with a knee injury.
The Cowboys were without starters Tony Romo, Jason Witten and Dez Bryant. Brandon Weeden, who came over from the Cleveland Browns, started at quarterback for the entire first half, finishing 13-17 for 107 yards and one touchdown.
