外电报道如下：Yao scored 14 of his season-best 30 points in the final period, but fouled out and could not prevent the Rockets from taking their seventh straight defeat, a 94-89 loss to the Chicago Bulls.

　　Foul在体育比赛中，如足球、篮球、拳击中，可表示“犯规”，比如：a foul boxing match（拳击比赛中犯规的一击）；报道中提到姚明“被罚下场”，用的是foul out。Foul 是“犯规”，那么foul out就是因犯规超过限定次数而被罚下场。此外，disqualification也经常用来表达此意，简写为DQ。
