Doncaster Knights face a nervy end to their National One promotion bid after suffering a narrow defeat at title rivals Rosslyn Park.
Clive Griffiths’ men were playing catch up all afternoon in London and in the end had to be thankful for Mat Clark’s late try which grabbed a potentially crucial losing bonus point.
Park’s win ended Doncaster’s seven-game winning streak and cut their lead at the top of the table to four points with just three games left to play.
Both Knights and Rosslyn Park must face third-placed Coventry before the end of the season.
Park host the Midlanders next Saturday, while Doncaster face a tricky trip to the Butts Park Arena on April 12.
Two Dougie Flockhart penalties kept Doncaster in the hunt at half time, as they trailed 11-6 to Rosslyn at the break.
Scott Seddon nudged the hosts a further three points ahead with a penalty but Griffiths’ men sensed blood when Bruno Bravo set up Tyson Lewis to score in the corner. Flockhart converted to reduce the deficit to one point.
However, Park took the sting out of the visitors in the closing stages when Jack Gash seized upon a split ball and ran clear to touch down.
Sneddon’s conversion made it 21-13 but Clark’s vital late try earned Doncaster a precious bonus point.
Knights host Wharfedale on Saturday now knowing they still require 12 points from their remaining three games to secure promotion back to the Championship.
After going to Coventry, they finish their season at Blackheath on April 26.
