Someone pointed out on ESPN radio that this guy is really only losing these deals because his swimming career is likely over -- and his value to an endorsement partner would have been about $0 once the Olympics ended anyway.
Swimmer Michael Phelps currently has $12 million in endorsement deals, with likely more to come, as he is the most decorated Olympic athlete of all time. At this time, Phelps has left behind his endorsement deal with Speedo, and has a deal with Aqua Sphere (for an undisclosed amount). Additionally, his sponsor list now includes Under Armour, Omega, Master Spas, Sol Republic headphones, and 800razors.com, according to the Baltimore Sun.
