Harlequins and England U20 rugby union player Seb Adeniran-Olule has been killed in a car crash. The 20-year-old prop won the Six Nations for his age group last year and had burst into the Quins first team this season.

Adeniran-Olule had been with West London club since he was 13 and rose through its academy. "Harlequins are deeply saddened to learn the news of the untimely death of Seb Adeniran-Olule in a road traffic collision," the club said in a statement.

Conor O'Shea, Harlequins director of rugby, added: "Our thoughts and prayers are with Seb's family and friends at this difficult time. Seb was an incredible talent and had already represented England, as well as making his senior debut for Quins at just 20. He will be sorely missed by the whole squad as well as by the wider club."

Adeniran-Olule made his England U18 during a 43-12 win over Wales at Neath in March 2014. He first appeared at U20 level in the 19-14 victory over Ireland in Dublin in February 2015 and started the final two games of that Six Nations against Scotland and France, also appearing in four of the five matches in the 2015 World Championship in Italy.

The Rugby Football Union's national academy development manager John Fletcher paid tribute to Adeniran-Olule, saying: "I'm devastated, he was a fantastic kid. He was one of the most skilful players in his position I have ever seen. He always played the game with a big smile on his face and could do some phenomenal things with the ball.

"As a character he was quiet, had incredible work rate, was popular and first to learn. On the pitch he would get you off your seat and as a front-row player that is fairly rare. He had some outstanding moments with the ball in hand. He should be remembered as a great kid, I loved coaching him. It's a tragic loss."
