Humphries ‘Pumped Up’ During First Workout : Chargers: New quarterback is taking crash course on the system in preparation for Friday’s exhibition game.

LA JOLLA —  Quarterback Stan Humphries stepped onto the Charger practice field for the first time Sunday and promptly watched as two of his four passes were dropped.

Welcome to San Diego, Stan.

Apparently Humphries was unaware of the difficulty Charger receivers have had catching a football last year. He dismissed the drops as receivers having a cases of “jet lag.”

Humphries also took some of the blame, saying he was overthrowing during the light workout.

“I was out there excited and a little pumped up,” he said. “It’s hard to play quarterback when you’re so emotional and excited like that. You have to back yourself down to an even keel and just relax and play. The balls were coming out high because I was a little pumped up.”

Receiver Yancey Thigpen, who dropped one of Humphries’ bullets on the sideline, said Humprhies threw a “good ball.”

“I just dropped that because of a lack of concentration on my half,” he said. “He’s got great touch.”

Said Charger Coach Bobby Ross: “I didn’t even pay (Humphries) much attention.”

Humphries acknowledged that he probably also looked a little chunky at 238 pounds.

“I’m probably not in as good a shape as I should be in because the off-season went so poorly,” said Humphries, who was acquired in a trade last week from the Washington Redskins. “It’s hard to get excited and get where you want to be when you come into a situation like (Washington’s). I think I have a new life now. I’m going to do whatever it takes to get it right here.”

Since arriving in San Diego on Saturday afternoon, Humphries has spent much of his time with quarterbacks coach Jack Reilly learning the system. Reilly said he will prepare Humphries for action Friday against San Francisco by filling his head each day for two hours with terminology and formations.

Reilly said Humphries has handled the crash course on the Chargers offense well.

“There’s so many nuances and little adjustments that you have to understand,” Reilly said. “If he hadn’t played in the Washington system, it would be much more difficult.”

Reilly said Humphries and two other quarterbacks will play Friday, but he didn’t say who would be the odd man out. Ross said he hasn’t made up his mind who will start Friday.

Bob Gagliano looked sharp in the two-minute drill. He didn’t throw an incompletion, and he hit running back Ronnie Harmon and receiver Robert Claiborne in stride with long passes over the middle.

Rookie Carlos Huerta ended the drive by drilling a 42-yard field goal. Jeff Graham looked tentative in the two-minute drill. On one play, he held the ball too long and then almost threw an interception.

But Graham recovered by tossing strikes to Jimmy Raye and Walter Stanley.

Charger Notes

Running back Eric Bieniemy’s sprained ankle healed quickly and he appeared to be running at full speed. Coach Bobby Ross said he expects linebacker Henry Rolling, who has missed most of camp with an ankle injury, to be ready for Friday’s game. . . . General Manager Bobby Beathard said he has not spoken to David Morway or John Adler, the agents for holdout defensive tackle Joe Phillips, since last Monday and he has no talks planned in the near future. Beathard said the next move is up to Morway and Adler. “There’s nothing we can do,” he said. “They’re making a big mistake.”
