Ilkeston ensured they remain firmly in the hat for a play-off place with a 20-13 victory at Kettering on Saturday.
The Elks need just a win against Spalding to secure second place, with title honours looking almost certain to have evaded them.
The Elks began well and took the lead just eight minutes in.
Steve Quinn stole a Kettering line-out and the Elks pack drove forward towards the line, Kettering were unable to stop the drive and Adam Corcoran emerged with the ball to get the first try on the board, unconverted by Jono Falls but both kickers were to struggle in the strong wind.
After another period of possession the Elks recycled quick ball and Marc Moore, Greg Taylor and Dan Taylor linked up well to free up Lewis Taylor on the wing. He showed great footwork to evade the defence and scored on 13 minutes to extend the lead to 10-0. Conversion missed.

A penalty reduced the arrears to 15-3 soon afterwards, but Ilkeston were to register again on 33 minutes.
