Team GB's Jack Green out of men's 400m hurdles

Great Britain's Jack Green has finished in last place in his men's 400m hurdles semi-final at the Olympic Games.

Green had been handed a favourable draw in lane four but he struggled to keep pace with the runners around him and could only finish eighth in a time of 49.54s.

However, Ireland will have a representative in Thursday's final after Thomas Barr produced the performance of his career to win the third semi-final.

Barr's previous best performance at a major competition came when making the semis of the 2014 European Championship but he powered from fourth to first down the home straight to win his heat in 48.39s.
