A while ago, I read an article saying how Nike-sponsored players are prohibited from having patches on their apparel advertising for other brands that the players endorse. Federer, Sharapova, Nadal etc all endorse other brands, such as Rolex, Omega, KIA etc...but none of these logos appear on their Nike gear. To my knowledge, no other apparel companies ban their sponsored players from displaying the logos of other brands that the players endorse. It is because of this condition in Nike's contracts that cause the WTA to make rule exceptions for players with such conditions in their contracts. WTA - Part IV, Section B(1)(i)(iii) http://www.sonyericssonwtatour.com/global/pdfs/shared/thewtatour/officialrules/rules.pdf However, Marion Bartoli was wearing Nike gear and at the same time displaying some other logos in her match the other day... http://i41.tinypic.com/209lklf.jpg Any comments?
