A little over two years ago, Nicolas Dalby sat on his stool between second and third rounds in his fight with a fellow undefeated opponent Darren Till, not sure what he had left to give. Dalby was the favorite coming into that bout in Dublin, but after nearly being knocked out with an uppercut late in the first round and an exhaustive second — where Till began to demonstrate the composure and skill that has made him a welterweight contender in 2018 — he had to dig deep. Sensing that slipping resolve, his coach, Tue Trnka, provided the shovel.
