No, Goldberg didn't get into a WWE hardcore match on Tuesday ... but he certainly looked like he did -- suffering a gnarly head wound while out on his farm in Texas.
A rep for the wrestling legend tells TMZ Sports ... Goldberg was getting work done on his property, when he accidentally knocked his noggin on his tractor -- opening up a big gash near his forehead.
In photos of the injury that the 56-year-old shared on his social media page ... you can see the cut was so bad, it poured blood everywhere.
