The Tevatron indeed saw something at the right mass, just after the first hints from LHC came in: https://news.fnal.gov/2012/03/tevatron-experiments-report-la...
It's unclear to me if it could have ever pushed this to enough sigmas to claim discovery.
Just out of interest, why do you believe this to be true? There existed particle colliders before the LHC, none were able to experimentally verify the Higgs.
