The inaugural event, featuring four Major League Soccer teams and four teams from Mexico's first division, opens tomorrow night, with the Galaxy hosting defending Mexican League champion Pachuca and Chivas visiting FC Dallas.

Beckham had been scheduled to attend today's news conference in Hollywood, but he stayed away to continue treatment. He has yet to participate in full training since joining the team on July 13.

"We can't keep running him around, dragging him to press conferences and events," MLS commissioner Don Garber said. "We just want him to get better."

However, Beckham's injury didn't prevent him and wife Victoria from attending a celebrity-studded welcome party last night at a downtown Los Angeles museum. The bash, hosted by Tom Cruise and Will Smith, lasted into the early morning hours.

"He is a very professional guy," Garber said. "He's not going to do anything that he doesn't think is going to support his ability to get better."

The English superstar played 16 minutes, including four minutes of stoppage time, in a 1-0 loss to Chelsea in his Galaxy debut Saturday night. The highlight was a corner kick he took near the end of the game.

ESPN today reported a preliminary overnight rating of 1.2 for the game in the nation's largest markets. When final numbers are released tomorrow, it could be the cable network's highest-rated soccer telecast. The rating is the percentage watching a telecast among all homes with televisions.

Garber said the ratings, sold-out attendance of 27,000, and domestic and international media interest was more than MLS had expected.

"It shows that people have a real desire to see the sport get a lot of attention," he said. "If you deliver the right things — good players, high-quality competition, some interesting side stories — than we have a chance to really break out of some of the clutter that exists in pro sports."

But first, the league needs Beckham in the lineup on a regular basis.

Galaxy coach Frank Yallop said that if Beckham is able to play at all tomorrow night, it wouldn't be until late in the game.

"We don't want to make it worse, and he's still a little bit sore," the coach said. "We're forever hopeful he'd be back in a uniform and running out for us as soon as he can — next weekend or the following Tuesday."

More realistic for Beckham is the team's second SuperLiga game against Chivas on Saturday. It has been moved to the Los Angeles Coliseum to handle an expected huge crowd.

Beckham's injury has "certainly added to the drama of what's been going on here the last week or so and for the next couple of weeks," Garber said.

The commissioner denied that pressure was exerted from sponsors and ESPN to get Beckham into Saturday's game.

"That just couldn't be further from the truth," Garber said. "Look at what we would look like if we had sponsor or commercial pressures forcing him to play a game, and having him get injured and never playing again. We'd be pretty dumb."

Beckham's biggest problem is swelling in his ankle, Yallop said.

"It's really tight in there," he said. "He was uncomfortable on Saturday, you could tell. It's going to be a little bit sore when he's playing, but not as sore as it was on Saturday. That's what we're trying to get to."

Beckham's designated stand-in at the news conference, defender Abel Xavier, didn't make it, either. The Galaxy had no players in attendance.

Garber acknowledged the league has "been putting a lot of pressure" on Galaxy players to do promotion, but his message to the team today was "practice and beat Pachuca."

The SuperLiga tournament features two four-team groups playing round-robin matches, with the top two teams from each group meeting in the semifinals Aug. 14-15. The final is Aug. 29, with the winning team earning $1 million — the largest soccer purse in North America history.
