So, According to a report from ESPN.com, Oakley – with whom McIlroy has an eyewear and performance apparel contract through Dec. 31 of this year – has sued McIlroy and Nike, saying they breached McIlroy's existing contract with Oakley when he recently signed a new deal with Nike.
McIlroy's deal with Oakley includes what is known as a "right of first refusal" – a contract clause that allowed Oakley to match any offer that included payments to McIlroy for eyewear and apparel. If Oakley wanted to match what Nike offered, its deal would continue into 2013 instead of expiring at the end of the year.
Oakley filed a lawsuit filed Monday in federal court in Santa Ana, Calif. The company says the damage that has resulted from McIlroy's refusal to renew with Oakley is "irreparable" and entitles Oakley to an injunction that would stop Nike and McIlroy from concluding or implementing their contract. Oakley is also claiming money damages and asserts that it has spent $300,000 on a photo shoot for the products McIlroy would have endorsed in 2013.
