Chesterfield striker Ched Evans has signed a 12-month contract extension with the League One club.

The 28-year-old joined the Spireites on a one-year deal in June and has scored seven goals in 24 appearances.

In October, Evans was found not guilty, following a retrial, of raping a 19-year-old woman in a hotel room in 2011.

He was initially found guilty in 2012 and served two-and-a-half years of a five-year prison sentence, but his conviction was quashed in April 2016.

In an exclusive BBC Sport column, world number one Andy Murray has been talking about the Australian Open after he beat Illya Marchenko in the opening round earlier today.

"The first round of a Grand Slam is always tricky, but I am glad to get through it," said Murray

"My first-round match against Illya Marchenko, the world number 95, was OK but it was hard going. It was tough conditions. The on-court temperature was in the high 30s, which wasn't easy.

"I didn't feel any extra pressure playing my first Grand Slam as the world number one. I felt nervous beforehand, but I get that before all Slams."

The Green Bay Packers kicked a 51-yard field goal with three seconds left to beat the Dallas Cowboys 34-31 and move to within one game of the Super Bowl.

The Cowboys had rallied from 21-3 down at half-time in Dallas to level the scores before Mason Crosby drilled a retaken effort through the posts.

Green Bay now face the Atlanta Falcons next weekend, with the Pittsburgh Steelers playing New England.

The Steelers beat the Kansas City Chiefs 18-16 in Sunday's late game.

James DeGale, who suffered damage to his ear and teeth during the contest (his gumshield was knocked out during the eighth round) has posted this picture on Twitter vowing to "still move forward".

To spend time in James DeGale's dressing-room after the fight was to be reminded of the brutal, even savage, reality of professional boxing at the highest level. His face was so different to the one he took into the ring, disfigured and discoloured to the extent that such a gripping, compelling contest has to be regarded as a career-shortening experience.

He turns 31 next month and still has the IBF belt to use as a potent bargaining tool in negotiating the final phase of a career that, with and without a vest, has spanned two decades.

But had he claimed a second world title - and with it the recognition as the number one super-middleweight on the planet - the hand he played would have been much stronger. George Groves and Callum Smith will be given chances to become world champions themselves in the coming months and victory for one or both would set up the possibility of a series of showdowns to match the Benn, Eubank and Watson years we still talk about today.

"I'm a prizefighter," DeGale told me in Brooklyn, emphasising the importance of securing his future financially. But as Joe Bugner once said, earning big money is only as important as retaining the faculties to be able to spend it. DeGale must take wise counsel from here on because when it comes to health, wealth and reputation, too few fighters leave the sport with all three intact.

James DeGale's failure to beat Sweden's Badou Jack at the weekend has cost him an all-British world title fight with Callum Smith, potentially at Liverpool's Anfield stadium.

Smith had been scheduled to fight the winner as he is the mandatory challenger for the WBC super-middleweight title, which Jack retained after a majority draw with DeGale in New York on Sunday morning.

Promoter Eddie Hearn said: "James DeGale wanted to fight Callum Smith and vice-versa. But it doesn't matter now." 

DeGale, who kept hold of his IBF title, is also looking for another fight with Jack but will have to wait for that.

So where next for DeGale? BBC Radio 5 live's boxing commentator Mike Costello gives his thoughts.

More from Sam Allardyce on Crystal Palace's problems: 

"Defensively we are conceding too many goals.

"That's an area of my expertise. I have started working with them in that area but it hasn't worked yet."

Finally, Allardyce is asked if attempting to keep a free-falling Palace in the Premier League is his toughest test as a manager:

"If at the end of the season I haven't kept them up, then it will be my toughest test."

Allardyce was asked about what was wrong with Palace, who are in 17th position in the Premier League and only one point above bottom club Hull.

"When I was at West Ham and Crystal came and thrashed us it was all about how good they were using the little possession they had," he said.

"The team has lost what it's used to be. The identity has changed."

On potential transfer targets, he adds: "I think we've exhausted this country and we'll be looking to Europe now."

Although "we appear to have an agreement with Arsenal [for Carl Jenkinson]".

Sam Allardyce explained further his logic for intending to rest some of his regular first-teamers in Tuesday's FA cup replay against Bolton:

"I can select the same team against Bolton and win and give us 15% less chance against Everton [in the Premier League on Saturday].

"Everton don't play this week at all. If you want to give yourself the best chance against Everton, you have to change the team tomorrow night."

It's been an uninspiring start for Sam Allardyce as Crystal Palace manager with three defeats and two draws since taking over.

Tomorrow brings an FA Cup replay third-round replay against Bolton and you probably won't be surprised to learn he is planning to change his side for the match at Selhurst Park.

He said: "It's a very good opportunity for squad players to play. Those saying 'get me in the team gaffer and I'll show you what I can do.'  

"We've got several players who can't play through injury, two at African Cup of Nations and we'll still be fielding an experienced side."

Despite nine defeats in the last 13 Championship matches, Norwich City are standing by their manager, Alex Neil.

I understand there are no plans to sack the manager who guided them to the Premier League in May, 2015. The belief at the club is that Neil will turn it round and that there's a need for stability in the dressing-room.
