An injury-ravaged Blackstones lost to Harrowby United in the United Counties League Division One.
The Stamford side went down 4-2 on Saturday.
Manager Gary Peace was forced to break up his strike partnership and play Adam Scotcher at the back with just one fit recognised defender available.
The visitors went ahead with a goal from Scott Webb.
A Lee Shaw brace looked to have put the game to bed but Addie Staffieri kept it interesting for Stones, notching a double of his own in the 71st and 73rd minutes to keep them in the match.
However, the revival lasted just a minute when John Currall scored a harsh penalty for the Arrows to secure the win.
Stones have a chance for revenge away tomorrow.
