Nuggets coach George Karl isn't against signing free-agent guard Allen Iverson.

Denver won 50 games with Iverson during the 2007-08 season.

Karl clarified that the future Hall of Famer will only be an option if the injury bug hits the club.

"A.I. for us is an injury discussion," Karl said. "I don't think it's an (overall) discussion right now for us. Say that Ty Lawson is out for the season. Speed and quickness is what Lawson gives us, so A.I. would be on the list of speed and quickness."
