Andrew Flintoff has had an operation to repair a torn shoulder ligament which is likely to end his boxing career after one bout, but the possibility of a return to cricket remains.
It is unclear whether Flintoff sustained the injury during his fight with American Richard Dawson last month or his many months of sparring, but it is serious enough for him to require surgery, which would leave him facing a long period of rehabilitation and physiotherapy if he decided to return to the ring.
His strict training regimen has left Flintoff leaner and fitter than at any stage of his sporting life and a return to professional sport reignited his competitive instincts, leading to thoughts of a cricket return.
The shoulder injury is serious enough for him to realise his boxing career is over despite offers to box in America. A return to play Twenty20 is one of many options on the table and he will make a final decision in the new year.
Amir Khan is targeting April for his return to the ring and hopes a rematch with Danny Garcia can be made for later in 2013.
After back-to-back losses against Lamont Peterson in December 2011 and then Garcia in July, Khan concluded 2012 on a more positive note last weekend with a 10th-round stoppage win over Carlos Molina in Los Angeles.
And looking to the year ahead, the Bolton fighter is planning for his next bout to be in around four months' time, with another showdown with Garcia – who added Khan's WBA light-welterweight title to his WBC belt when he beat him – to come after that.
"The next fight is going to be around April time," said Khan. "Then I want to be back in the ring again and then trying for the rematch with Danny Garcia."
London will make more sporting history by hosting the 2017 paralympic athletics world championships a month before the IAAF World Championships.
It will be the first time one city has hosted the two showpieces side-by-side after it was argued during the bidding process that London 2012 had justified the return of international paralympic competition to the city.
The championships, organised by the International Paralympic Committee, will be held at the Olympic Stadium in July. The athletics at the Paralympics drew sell-out crowds of 80,000 for every session and attracted more than a billion TV viewers worldwide.
