McColl and Roberts pay the penalty for Knights against London Welsh

Knights full-back Stevie McColl hit the crossbar with his last minute penalty from his own half. Fly-half Roberts also missed a chance five minutes earlier to put his side ahead and ex-Knight Jamie Lennard came out on top of the kicking dual in the end.

London Welsh got off to a flyer with Josh Draninui scoring after two minutes, Doncaster didn't deal with Claasens's high bomb and Draninui collected for a easy score, Lennard converted.

Roberts pegged the score back moments later with a drop goal. London Welsh got their second try soon after with Paul Mackey finishing off a sweeping move. Lennard couldn't convert this one but he added a penalty shortly after. With the half coming to an end Doncaster hit back, Andy Wright scored a neat try after being put in by scrum-half Nathan Jones.

Roberts was able to convert and he added a further score right on half time.

The second half started in the same manner as the first ended with Roberts slotting over penalty to put his side into the lead for the first time in the match.

Fifteen minutes later Lennard was at it again, edging his side ahead with a 40 yard penalty. Roberts then made his second drop goal, rewarding his forwards for their good work to put his side back in front.

Then came what turned out to be the crucial score, the Knights were caught offside and Lennard made his ex-team-mates pay with the three vital points.

In the closing minutes the visitors became nervous and conceded to sloppy penalties but neither Roberts or McColl late on were able to make them pay.
