In the Blackburn and District Badminton Association Second Division, second placed Roefield A, were surprisingly defeated by mid-table St Nicholas in Clitheroe.
The home side were in trouble right from the start, and at the halfway stage of the match were trailing 9-3.
An improvement in form produced further points but they eventually went down 15-5.
Blackburn Seniors B were favourites to record their seventh win of the season, but their visitors Stanhill had other ideas.
The home side were in trouble from the first game played, although the seniors did rally in the level doubles, but the result was never in doubt as Stanhill recorded a 12-8 victory
In the First Division, Telecom A, earned a well-deserved victory against lowly Tag by a very narrow margin.
The visitors were trailing 7-5 after the mixed doubles, but with a strong reply they were able to secure three of the men's doubles, and backed by their ladies they were able to level the match 10-10.
Telecom finished the better and recorded a victory 13-12.
Playing again this week, Tag went down to the second placed team Westholme A in a 22-3 defeat, enabling last year's champions to close the gap on leaders Blackburn Seniors A.
Westholme A still have two games in hand on the leaders. Telecom A gave the leaders a very competitive match as well this week, but finished on the wrong side, going down 13-7, meaning that Blackburn Seniors dropped some valuable bonus points.
Telecom are now third in the table.
