LAS VEGAS (AP) – Rocked by a recent spate of high-profile suspensions, UFC announced on Wednesday a multimillion-dollar anti-doping plan.

UFC says all fighters will be subject to random performance-enhancing drug testing, effective July 1.

UFC announced the decision one day after fighters Anderson Silva, Nick Diaz, and Hector Lombard were slapped with temporary suspensions for failed drug tests.

Light heavyweight champion Jon Jones also tested positive for cocaine before UFC 182.

UFC CEO Lorenzo Fertitta says the world’s leading MMA promotion will press athletic commissions to impose more severe doping penalties. Fertitta says he supports the World Anti-Doping Association’s two-year ban for first-time offenders and would have no issue with increasing the ban to four years if WADA goes that route.
