Welsby fumbled before Samoa’s Stephen Crichton kicked the match winning field goal and he put down a Nathan Cleary bomb that led to Brian To’o’s 79th minute try for the Panthers.
“I thought ‘what have I done’. It was reminiscent of the Samoa game where I knocked on and I thought ‘I have done it again for Saints’,” said Welsby, who was man-of-the-match in the 13-12 triumph.
“It is a similar group of lads who just worked so hard to get to where they are, and I have gone and bombed it again.”
