Allen Iverson's debut with the Memphis Grizzlies will have to wait because of a strained left hamstring.

He suffered the injury during a scrimmage on Sunday and was held out of the team's preseason opener against the Wizards on Tuesday night.

Iverson is scheduled to have an MRI on Wednesday in Memphis.

"I wouldn't even look at it as being safe or smart," Iverson told the Associated Press. "I can't go. If it was Game 7 in the finals, I wouldn't be able to go."
