BLACKSTONES must face rivals Deeping Rangers and title-chasing Long Buckby without their first choice goalkeeeper Lee Crockett.
Crockett suffered a broken arm during Saturday’s 3-1 victory at Irchester.
The Stones keeper came for a cross with 15 minutes of the game remaining and fell awkwardly. He will miss Stones’ remaining three games.
Joint Stones boss Michael Goode said: “We’ve brought Jerome Chambers up into the first team squad in the past but it will depend if he is available.
“We would like to have the same keeper for all three games.”
Stones face Rangers at Outgang Road on Easter Monday and the derby is followed by back-to-back games against Buckby to end the season - at Lincoln Road on April 18 and away on April 28.
Goode added: “It’s a real shame for Lee, who has done brilliantly this season.”
The injury marred a comfortable victory for Stones who were already ahead by the time the hosts were reduced to 10 men. Craig Lawman was sent off for an off-the-ball incident involving Tim Quy.
Irchester took an early lead capitalising on poor Stones defending after four minutes. But from that point, the Stamford side was in charge.
Simon Mowbray converted two of his more difficult chances either side of a Michael Nelson penalty awarded for a foul on Quy.
