I think Nike does not allow players to place other sponsors on the clothes...
Correct, if they would Sharapova's dress would probably be plastered all over.
Nike players aren't allowed to display sponsorship badges, the only exceptions being the Chinese players as they have an exemption that precedes the current Nike deal.
