The Alzheimer's Society welcomes the news that all professional rugby union players and coaches in England will have compulsory education on concussion before the start of next season.

"Evidence suggests that head injuries can increase a person's risk of dementia, so it's good to see both rugby players and their coaches are now being made aware of the potential seriousness of concussion," read a statement.

'Previous studies indicate that it's the inflammation which occurs following head injury that may encourage the formation of the plaques and tangles which are hallmarks of Alzheimer's disease."

BBC Sport's Shamoon Hafez: "Scenes similar to Cliff Richard at Wimbledon all those years ago look like taking place at Alexandra Palace this afternoon. Rain hasn't stopped play, but a power failure means the arena has been plunged into darkness. MC Rob Walker tries to keep the crowd entertained, while a cameraman has gone off to get his guitar, according to snooker journalist Dave Hendon.

"Shaun Murphy has taken to Twitter to say he has never experienced something like this before, while Ding Junhui - in darkness - sits calmly backstage eating an apple."

Former Manchester United defender Gary Pallister feels teenage forward Adnan Januzaj, 18, has shown his strength of character with the way he has dealt with rough treatment from opponents since breaking into the United first team.

"Adnan deserves credit, because players are targeting him as he is a threat," Pallister told United's official website., external

"He's young and he's not grown into his body just yet, it looks as though he is getting whacked and picked upon. But the great thing about him is that, a bit like Cristiano Ronaldo when he first came here, he picks himself up, dusts himself down and attacks them straight away."
