Dylan Hartley has been confirmed as England captain for the Six Nations and was accompanied at Wednesday's tournament launch in London by a bruised Eddie Jones.
Hartley will continue as skipper for the grand slam defence despite being sent off for striking Sean O'Brien during Northampton's defeat by Leinster on December 3, an offence that resulted in a six-week suspension.
While Hartley was questioned on stage during the Q&A of the annual Championship curtain raiser in south London, Jones watched on from the audience with a wound dressing around his left eye, which was bruised.
Jones later revealed that the bruising was caused when he fell over in the bathroom of his London hotel after initially joking that it had been sustained while attempting the combat sports England's players have been practising since October.
"First we had judo and then we had MMA, so we're just going through all the martial arts sports to see what effect they have on the body," Jones said.
"I slipped over in the hotel this morning. My mother always told me I've got to shave and I forgot to shave; I walked out of the shower to get the shaver and this is what happened. I follow what my mother says."
Jones then said he got the injury while on the recent training trip to Portugal.
"Tough old training camp, mate," Jones told a reporter. "I just slipped over and got my head cut at training, but no big deal."
Jones is preparing for the defence of the Six Nations title after opening his reign with 13 straight wins last year.
By the time France visit Twickenham for the Six Nations opener on February 4, Hartley will not have played for nine weeks and his disciplinary record now consists of 60 weeks worth of bans.
When questioned about his match fitness, Hartley said: "We did this last year talking about me, I'm here on behalf of the team.
"The challenge is to use this week as best we can to get the preparation right for a huge first game."
