Philadelphia ? It didn’t cost anything for corporate sponsors and others to attend a 76ers meet-and-greet Wednesday night at the Lucky Strike Bowling Lanes.

It cost Allen Iverson a substantial amount of money for not attending.

Coach Maurice Cheeks confirmed that the Sixers’ captain was the only player not to make a mandatory appearance at the event, and said he “will be fined accordingly.”

The Center City event was attended by about 300 sponsors, premium seat-holders and some season ticketholders.

“We would have liked him to be there, but he wasn’t, and that was his choice,” Cheeks said. “I can’t speculate on why he wasn’t there, but he wasn’t there.”

A source said Iverson was upset when he left practice earlier in the day, less than an hour after the 11 a.m. start at Philadelphia College of Osteopathic Medicine.

After practice, Cheeks said Iverson had left early because he “was a little fatigued.”

Asked whether Iverson had been upset, Cheeks said, “Whatever happened between him and me, I’d like to keep that private.”

Iverson was coming off a 45-point performance in Monday night’s 103-91 loss in Miami in which he shot 17-for-37 from the floor. Since missing two games because of dental surgery to have an abscessed wisdom tooth removed, he has accumulated 122 points in three games, including a loss to Detroit and a victory over Chicago.

In mid-October, Iverson said that the players last season took advantage of Cheeks, a former star guard with the team who also had served as an assistant coach. Last season was Cheeks’ first as the head coach, succeeding the fired Jim O’Brien.

“It’s always like that in life, it’s always like that,” Iverson said at the time. “As a parent, you know your kid is always going to take advantage of you if they can. Anybody in life will try to take advantage if they can.

“It’s just been that way. If somebody’s easygoing and they’re laid-back, you’re going to expect them to be that way all the time, and you’ll act accordingly. That’s the way it’s probably been, even (with) myself, just knowing Mo Cheeks and knowing him as a person, not really knowing him as a head coach.

“It was kind of (easier) than it had been for me. I had tough coaches. It was real different for me.”
