FRANKFURT, Germany (AP) -- Former Force India Formula One driver Adrian Sutil says Lewis Hamilton is a "coward" for not testifying at the German's trial.

Sutil was convicted of causing grievous bodily harm in a nightclub confrontation in China and given an 18-month suspended sentence Tuesday. Hamilton declined to testify because of commitments with his McLaren team.

Sutil told the Bild Newspaper that "Lewis is a coward, I don't want to be friends with someone like that."

Hamilton witnessed the incident at a party following Hamilton's victory at the China Grand Prix in Shanghai last April, when Sutil cut Renault team executive Eric Lux in the neck with a champagne glass.

Sutil said he intended to spill his drink on Lux, and that causing the injury was completely "unintentional and accidental."
