"I wish things hadn't happened the way they did," the Scottish Sun quotes Higdon as saying. "I'm annoyed at myself for getting myself into a situation like that because it's not me.
"I'm not the type of lad who goes out clubbing or to bars. I'm a country-pub type of guy. That's the disappointing aspect of it because I think this was avoidable. I should have known better than getting into that kind of situation."
Meanwhile, the Scottish club are thought to be keen on offering the striker a new contract.
