Miami coach Pat Riley expressed relief Tuesday over the news that Heat forward Antoine Walker was not injured during a robbery at the player's Chicago home.

Walker and one of his relatives were bound at gunpoint while multiple robbers took a car, cash and jewelry from the three-time All-Star's offseason residence Monday night.

Walker -- a Chicago native -- was shaken up, but not physically injured, said agent Mark Bartelstein.

"I've talked to Mark. Have not been able to get through to Antoine yet, but he's OK," Riley said Tuesday after watching the Heat's summer league team play. "It's what it is. It had to be a terrifying ordeal for him. Until I speak with him, I don't have any knowledge other than what I've heard from other people."

The vehicle taken in the robbery was found, abandoned, in Chicago on Tuesday morning.
