Comedienne and actress Chelsea Handler is nursing a swollen ankle after taking a tumble during a tennis lesson.

Jennifer Aniston's "injury-prone" best friend recently slipped on a ball while practising her form on the court and now she is hobbling around as her left foot heals.

She explains, "This week I was playing tennis with a coach, an instructor who's meant to guide me so that I don't hurt myself, and I managed to roll my ankle on a ball, dive over the court, land on my face, but I don't have any bruises (on my face), so that's good... It was embarrassing. (My ankle)'s all swollen."
