CARSON, Calif. -- Much like the past two years in San Diego with the team struggling on the field, opposing fans made their presence felt in the debut of the Chargers in Los Angeles.

Los Angeles Chargers quarterback Philip Rivers said he knew rookie kicker Younghoe Koo missed the potential winning field goal from the reaction of Miami Dolphins fans.

“Obviously the loudest roar came at the end after the missed field goal, to where you really got to see how many Dolphins fans there were,” Rivers said. “I heard the roar before I saw the official’s signal.”

Koo pushed his 44-yard field goal attempt wide right, letting the Dolphins escape with a 19-17 win and putting the Chargers at 0-2 for the first time since 2008.

Chargers running back Melvin Gordon also noticed the strong contingent of Miami fans.

The Chargers announced a crowd of 25,381 for their first game at the StubHub Center, the 27,000-seat home of Major League Soccer’s LA Galaxy. For the most part the place was full.

“It was crazy,” Gordon said. “There were a lot of Chargers fans and there were also a lot of Miami fans. I think it was around 50-50, but it was nice to see a full house.”

During the lame-duck year at Qualcomm Stadium last season in which it became apparent the team would move to Los Angeles, opposing fans regularly took over the stadium, including a December game against the Oakland Raiders in which the facility was filled with about 80 percent Raiders fans.

However, guard Matt Slauson took solace in the fact the Chargers’ offense was not affected by the noise coming from opposing fans.

“It was good,” Slauson said. “You know the Dolphins travelled well today. We didn’t have to use our silent count, so that was nice. I think it was a good crowd, a lot of energy there.”
