Mike Leonard provided yeoman service for Grange hockey for a number of seasons as a player.
But the former Scotland captain, who is now coach to Watsonians, is on the opposite side tomorrow at Fettes, 2pm.
Leonard’s men, who are sixth in the table of ten, travel across town following a 6-0 home defeat by Western Wildcats last Sunday.
Grange, in contrast, beat Uddingston Deans Eng 6-3 at Fettes and Edinburgh University 2-1 at Peffermill.
The six points earned edged them one point ahead of long-term Division One pace-setters, Bromac Kelburne, in the race for the title with three games remaining.
Leonard said: “We were disappointed on Sunday but three points from the win over Edinburgh University from a good performance was pleasing.
“There will be pressure on Grange as they are at the top of the table and we are missing a few, but you never know.”
Grange will be at full strength but senior player Andrew Brogdon said they continued to take one game at a time.
He added: “It is a good position to be in and it is in our own hands but we are only focused on our next game.”
Edinburgh University, who are seventh, face a must-win home clash with Hillhead (push-off 4pm) who have 14 points and are one point adrift in eighth position.
