Definition of "stubbled"

The crew assistants ferried coffee to higher-ups, and a stubbled young actor in a brown velvet blazer paced about, wearing an iPod. He had the magazine-ready looks of a soap opera actor, and that is what he was — the co-star of a Greek soap opera that chose this Greek-heavy neighborhood as its actual and on-screen location.
