Ghana international, Bernard Mensah, halted his preseason training with Atletico Madrid due to illness.
The young attacking midfielder could not continue the workout after vomiting on the pitch due to the physical pressure imposed by Coach Diego Simeone.
The former Gomoa Feyenoord enforcer eventually returned to the locker room without touching a ball.
Bernard moved to Atlético Madrid on a six-year deal last year and was loaned out to fellow La Liga side Getafe CF.
The 21-year-old made 10 appearances for Gatefe last season
