Carl Froch recently had a quick check-in at a hospital, dealing with his recurring eardrum problem, but the UK fighter says it's nothing serious:
Froch told BBC Radio Nottingham: "I have just come out of the hospital but it was nothing serious.
"I had a bit of a blocked left eardrum from a couple of punches I took. I think a bit of wax was pushed against the eardrum so I had that cleaned out."
The Nottingham boxer is looking to retain his crown, after winning it for a second time with a unanimous points win over Arthur Abraham in Helsinki in November.
Despite the hospital visit, Froch is keen to allay fears about the seriousness of a problem with his ear.
"I feel unblocked, clear headed and back in balance again, so other than that I feel in tip-top shape and ready for business on Saturday night," he said.
Froch, who turns 34 on July 2, has struggled with the ear problem over the years, but it has yet to truly hamper him in the ring. He faces Glen Johnson on Saturday, with the winner heading to the final bout of the Super Six World Boxing Classic against Andre Ward, which is tentatively set for later this year.
