Which sporting traditions would you ban? Some selections from the BBC Sport Facebook page.
David Moore, external What seems to be now a "tradition" of being born in one country but playing for another, it doesn't matter if your great grandparents once went to France on a holiday. The country you are born in is the country you can represent at international level... If you don't like it, don't represent anyone.
Colin Holmes, external Net call on tennis. You don't stop a point half way through it it clips the net - it's unlucky, but you deal with it. Some time it works for you, others not.

Kyle Edmund is getting plenty of court time at the Flanders Expo ahead of the Davis Cup final - he's back on court this afternoon with hitting partner Dan Evans, and deep in discussion with GB captain Leon Smith.
The 20-year-old from Yorkshire could be in line to make his Davis Cup debut on Friday, with the more experienced James Ward the other contender.
Klitschko v Fury workout

BBC Sport in Dusseldorf
Wladimir Klitschko has arrived an hour early for his workout at Dusseldorf airport so we are now being treated to the curious sight of the champion sitting ringside watching the challenger Tyson Fury go through his paces, while gentle airport muzak is piped in over the top.
It gets weirder and weirder and weirder...
Especially when Fury finished off his public workout by serenading Klitschko with a 'version' of Bette Midler's 'Wind Beneath My Wings'.
It was quite touching but I felt it lacked Midler's sense of longing and gravitas.

India end the first day with a flourish on a fierce turner in Nagpur by reducing South Africa to 11-2 at stumps.
Spinners Ravichandran Ashwin and Ravindra Jadeja were brought on almost straight away, removing opener Stiaan van Zyl and nightwatchman Imran Tahir respectively.
The hosts earlier posted 215 as they look to extend their 1-0 series lead.
Football
Dynamo Kiev have been ordered to play their next three Uefa home matches behind closed doors and fined 100,000 euros.
The punishment follows a charge of racist behaviour and crowd disturbances during last month's Champions League clash with Chelsea in Ukraine, the governing body has announced.
The third of the behind closed doors matches is suspended for a probationary period of three years.

Today marks quite a major anniversary in the world of football ... 10 years since the death of the great George Best.
One of the greatest players of all-time, Best scored 137 goals in 361 games for Manchester United during the 1960s and 70s, dazzling the world with his wonderful skills.
The Lionel Messi of his era on the pitch (even Pele described Best as the finest player on the planet), he was also quite a character off it - famous for quotes like ... "In 1969, I gave up women and alcohol, it was the worst 20 minutes of my life."
In later life, Best suffered health problems and died in 2005, three years after having a liver transplant.

A public workout in an airport departure lounge at least makes for a captive audience.
Tyson Fury arrived half an hour early for his stint in the ring and is incredibly relaxed, giving plenty of time to the assembled media and promising to stick around for Klitschko's stint, which kicks off at 1200 GMT.
"I will torment him," says Fury.
Who knows what he's got up his sleeves today, but his sleeves are as wide as a wizard's.
Cricket
Cricket officials have tweaked the normally predictable Adelaide Oval pitch to help bowlers in the third test between Australia and New Zealand starting on Friday.
Batsmen have dominated the traditionally bowler-friendly pitches so far.
Adelaide head curator Damian Hough said he was deliberately leaving more grass on the pitch for the inaugural day-night test.
"Leaving a bit of grass on it, we're hoping it will assist the quicks and the ball will come onto the bat nicely,'' Hough said. "But having a bit of a coarse, thatchy grass should hopefully help the pink ball bite into that grass and get some spin.''

Arsenal, Tottenham and Liverpool are all considering making a bid for Brazil forward Alexandre Pato, 26, in the January window.
Pato is currently out on loan at Sao Paulo from Corinthians.
