"Tony Allen and O.J. Mayo were involved in a physical altercation Monday afternoon over a gambling debt during the Grizzlies' flight home from Los Angeles.

Team officials insisted that Mayo's absence Tuesday night for the Grizzlies' 110-105 victory over the Oklahoma Thunder was due to bronchitis and not the fight. But the incident was described as a one-sided scrap in which Allen clearly got the best of Mayo.

Neither player was disciplined after meeting with coach Lionel Hollins once the team arrived in Memphis.

According to a source, Mayo and Allen were involved in a card game that left Mayo owing Allen between $1,000 and $1,500. Mayo refused to pay and repeatedly insulted Allen."
