The decision not to test Shane Carwin for prohibited substances at UFC 131 came from a group affiliated with the local commission that conducted the tests, a representative for the former UFC interim heavyweight champ said today.
Carwin manager Jason Genet confirmed to MMAjunkie.com that following the fight, Carwin offered to submit a urine sample for testing – but immediate medical concerns prompted officials to forgo the test.
Carwin was among six athletes selected for drug testing following UFC 131, according to test results released Tuesday by the Vancouver Athletic Commission.
