SAN DIEGO, Aug. 11 (UPI) -- Chris Griesen threw a 15-yard touchdown pass to Bryan Gilmore in the third quarter Saturday night, leading the Arizona Cardinals to a 24-17 exhibition victory over the San Diego Chargers.
The untested Griessen, entering his first season as Jake Plummer's backup, completed 6-of-11 passes for 74 yards. His TD pass to Gilmore with 6:09 left in the third quarter gave the Cardinals a 21-17 lead.
Plummer played the first quarter and hooked up with muscular wide receiver David Boston on a 66-yard touchdown pass. Plummer went 5-of-7 for 101 yards.
While Plummer firmly is entrenched as the Cardinals quarterback, veteran Doug Flutie and second-year pro Drew Brees are waging a battle to win the job in San Diego.
The incumbent, Flutie started and went 6-of-9 for 46 yards.
Brees was 8-of-13 for 60 yards. He also had interception returned 38 yards for a touchdown by David Barrett.
Third-stringer Dave Dickenson had a 15-yard touchdown pass to Pat Batteaux in the third quarter for the Chargers, who lost in the debut of new coach Marty Schottenheimer.
