Federal senator Derryn Hinch has been hospitalised after a fall from an Uber in Melbourne.
Senator Hinch, 74, said he spent Monday night at The Alfred Hospital in Melbourne after being diagnosed with what he called "slight brain trauma" from the tumble on St Kilda Road.
"I stepped on the kerb and I fell over and I banged my head and I ended up in The Alfred hospital," he told Sky News.
"They kept me in overnight and did some tests — heart tests and blood pressure tests and various things."
Senator Hinch, who had a liver transplant in 2011, said he had two glasses of wine at dinner.
"Was I pissed? No I wasn't," he said.
"I'd had two glasses of wine with my dinner guest that night at their house and I came home and it all happened outside my house. I drink occasionally and I'm not stupid."
Senator Hinch was released from hospital but will return for further tests.
He said he was feeling "fine".
"What scared me most was that I had to fly to Canberra … for a war memorial thing with Brendan Nelson and Ben Quilty, so I want to make sure I can actually fly," he said.
"I can't stop myself from falling over — old people do that."
