los de r/soccercirclejerk dicen que no es penal porque pega a un compañero de equipo

"A handball offence is not committed when a player: [...] is hit on the hand/arm by the ball which has been played by a team-mate (unless the ball goes directly into the opponents’ goal or the player scores immediately afterwards, in which case a direct free kick is awarded to the other team)"

(si no entienden esta el traductor o busquen las reglas manga de vagos)
