The Greens lost their second home BT Premiership match when newcomers, Marr, won 23 19 at Mansfield Park.
The visitors had a lively first half with the home side bouncing off tackles and they led 20 0 at the break. The scoreline was all the more remarkable as the Ayrshire team were given three yellow cards in the first half while Guy Graham also had a yellow card for the Greens.
Dalgleish and Jackson were the try scorers for Marr with Chris Sturgeon landing two penalty goals and two conversions.
Strong words must have been said at half time by the Hawick coaches as they came out a different side for the second half.
The Greens managed three tries by Lewis Ferguson, Kyle Brunton and Edinburgh Rugby full back Tom Brown. Ali Wear converted two of these tries.
With the score at 20 19 for the visitors Hawick hammered away trying to get the win, but It was Marr who landed a penalty goal with the last kick of the game.
Hawick coach, Darren Cunningham, said: “We prepared well for this game and started confident that we could put a performance in at Mansfield, but poor tackling and a lack of discipline put us under pressure from the start and we soon found ourselves 20 points behind. There was some harsh words at half time and we started much brighter in the second half. We cut the stupid penalties down and clawed our way back into the game... building phases in attack and we were more accurate tackling in defence scoring 3 unanswered tries but was still not enough losing out 19-23. A much better second half but we need to learn that we can't give any team a 20 point head start in the Premiership if we want to win games. “
