Heat coach Pat Riley called out Antoine Walker on his conditioning Wednesday and said the forward might not approach the shape the team desires until January.

"It's beyond irritating," Riley said before his team faced Atlanta in an exhibition at AmericanAirlines Arena. "I'm beyond being irritated. I was irritated the first year when I signed him. I was really irritated last year. I'm beyond irritated. I don't have time to be irritated."

Riley rarely discusses players' conditioning status, but said Walker reported to camp earlier this month at 262 pounds and 15 percent body fat. The 6-foot-9 veteran is listed by the team in its media guide at 245 pounds.
