Thomas Barr has now QUALIFIED for the semi-finals of the 400m hurdles of the World Athletics Championships in London
Barr originally missed out on one of the four automatic qualification spots after finishing his heat in 5th place - one hundreth of a second from 4th in a time of 49.79 seconds.
However Kyron McMaster who finished 2nd was later disqualified by officials, after replays showed he stepped on his inside line.
That decision moved Barr up to 4th, and into the semi-finals which take place tomorrow night.
