Pro golfer Vijay Singh filed a lawsuit against the PGA Tour on Wednesday, seeking unspecified damages for the “public humiliation and ridicule” that the tour allegedly subjected him to during its 12-week investigation into Singh’s use of deer antler spray.

Singh wasn’t looking to keep his antlers shiny. Deer antler spray is purported to contain an insulin-like growth factor, and it was on the PGA Tour’s list of banned substances. In January, Singh told Sports Illustrated that he used the spray and was “looking forward to some change in my body.”

Though a sample from Singh showed small amounts of insulin growth factor, the tour dropped its investigation on April 30 because, according to the World Anti-Doping Agency (WADA), deer antler spray contains such small amounts of the growth factor that it is no longer banned.

Singh’s lawsuit alleges that the tour did not research the performance-enhancing effects of deer antler spray, and just relied on WADA’s list of banned substances. Singh also accuses the tour of holding $99,980 of Singh’s earnings from five tournaments in escrow without the authority to do so. The suit claims that Singh’s caddie suggested he try the spray to help with Singh’s back and knee injuries.

Singh’s lawyers claim that the PGA Tour “rushed to judgment and accused one of the world’s hardest working and most dedicated golfers of violating the rules of the game,” ESPN reports.
