Pau Gasol missed the Lakers' shootaround prior to their sleepy loss to the Grizzlies on Sunday night.

Gasol slept too late due to an iPhone malfunction.

"My alarm didn't go off so I woke up past the time," he said. "I still went to shootaround, just a little later than I should have been."

A team official said Tuesday that Gasol missed the team's entire morning shootaround.

Three Lakers in all said they did not get up on time because the alarm clocks on their iPhones malfunctioned Sunday morning.

Luke Walton was one of the other two Lakers who arrived late. The third Laker was not identified but sources said it was not Kobe Bryant.

Widespread alarm issues had been reported by iPhone users across the world citing a New Year's glitch with the Apple product.

"I always think that it affects the team's performance when everybody is not in their places ready to go when it's 10 o'clock in the morning and we're supposed to be ready to go through a film session," Phil Jackson said.

"Then everybody is behind a little bit and everybody is wondering what happened to somebody else and then the messages conveyed aren't there in the same way. So, it affects [the team], but you have to be grown up enough to know that you can't let that affect your own game."

Sources say Gasol's absence only fueled Bryant's frustration with the team, underscoring the lack of commitment and focus the team has displayed.
