Yet another setback.

Alonzo Mourning missed Monday's game against Utah with flu-like symptoms, which he felt upon arriving in Utah on Sunday evening.

Mourning, who stayed in his downtown Utah hotel room Monday night, missed five games this season, and was physically set back for several weeks, because of complications from a virus that was initially thought to be food poisoning. While early indications are that this illness is not as serious, Mourning's kidney condition makes any illness a sensitive situation.

"He has a cold, so he's not feeling good," Heat coach Pat Riley said. "Last time was a virus, intestinal virus, just sort of sapped him. I just hope this is just a case of the flu, maybe 24-hour stuff. We'll have to wait and see."

Mourning seems to have picked up the flu from his family, which came down with an illness one at a time. The doctor who was treating Mourning's wife, Tracy, and two children, warned Heat trainer Ron Culp of the likelihood of Mourning picking up the flu and gave Culp the necessary medications in case he did.

When he had the virus, Mourning was unable to hold down any solid food or his kidney medications. That is not the case this time, as Mourning has been able to take his medications.

"Every time Alonzo gets a hangnail, I don't think we should be that concerned about it," Riley said. "They said (the flu) was running through the house. When you got kids, it just sort of spreads."

Mourning missed the shoot-around Monday, but his status for tonight's game in Denver is uncertain. While his illness may not be as serious as the last one, this has come at a worse time. Mourning and the Heat have been playing their best basketball of the season, having won 7-of-8 entering Monday's game.

In his past five games, Mourning has averaged 16.4 points, eight rebounds and 2.2 blocks while shooting 65 percent (20-of-31) from the field.

The All-Star Game reserves will be announced today, and Mourning is a long shot for a spot on the Eastern Conference squad. Dikembe Mutombo was voted onto the team as a starter, and Indiana's Jermaine O'Neal is the likely selection as the backup center.

Mourning's best chance to make the team is as a replacement for a player who sits out with an injury.
