Valley were held for a second time this season by March Town United after an entertaining encounter at Butlin Road.
Despite being a stop-start affair and one lacking real quality too, it was still an absorbing game full of incident in front of a noisy 345-strong crowd.
With both Keenah Rosser and Alex Lock ruled out through injury, there were recalls to the starting eleven for Josh Thomas and Ryan Seal, as Town looked to return to winning ways on home turf following their surprise defeat to Desborough there eleven days earlier.
The first keeper called into action was Rugby's Matt Hill though, when he had to stretch up high to keep out Liam Francis's header towards his own goal.
Valley had to wait until the 15th minute for their first chance of the game, when a Francis header at the correct end was pushed around the post by Hill's counterpart Charlie Congreve.
Luke English was the next to threaten with his head when forcing another decent save by Congreve, after the wing-back had put in a strong effort to Seal's floated free-kick.
From the resulting Seal corner another English head went wide of the target, before English's cross from the right was just a little too deep for his team-mates.
Town nearly broke the deadlock when yet another English header was helped onto the bar by Loyiso Recci - also with his head, although March were soon reminding the hosts of their potential threat with a deflected strike from the edge of the area by Craig Gillies which was taken high by Hill.
Recci and Thomas then also did well to snuff out Jack Friend, after Hill had missed an attempted punched clearance.
English's effort from a tight angle was straight at Congreve, with another one from the same player shortly after drifting wide, before Rugby took the lead on 42 minutes - predictably with a header - with Recci's downward contact to Seal's corner squeezing between Congreve's legs and across the line.
Friend should have done better when he pounced on a Thomas error to end up with a run on goal, but his shot was weak and easily gathered by Hill.
Just ahead of the half-time whistle, Elliott's scissor-kick to Jordan Wilson's cross was blocked - with English's follow-up effort also smothered away.
Referee Brian O'Sullivan's increasingly erratic contribution to proceedings was highlighted by the red card issued to Town kit man Mark Cross shortly after the restart, with the next significant intervention from the match official seeing Wilson harshly punished for a handball just outside his box.
Danny Emmington duly stepped up and pinged the awarded free-pick past Hill and in off the underside of the bar to level things up, and then the visitors struck again on 59 minutes taking the lead when Friend followed up on Hill's good save to Gillies's header to score despite the best efforts of Thomas on the line.
There was further controversy six minutes later concerning Town's equaliser, which came after Edwin Ahenkorah's shot on the turn was saved by Congreve but then knocked back towards the goal by Emmington and was adjudged to have crossed the line before Harry Edwards cleared it away.
Once Hill had dived full length to keep out Sam Murphy's low strike from twenty-five yards and then Recci got back sharply to deny Friend with a covering challenge, it was the home side that arguably looked the more likely to grab a winner in closing twenty minutes.
Town had to play half of that time without the services of their skipper however, with Recci sinbinned for questioning the judgement of the frustratingly attention-seeking referee.
Sub Madundo Semahimbo's cross was clipped wide by the back of Wilson's head, before Semahimbo struck the base of the upright after English had played him in.
A Francis header to a hooked Kolodynski cross was saved by Congreve, Wilson was denied a run on goal by a tight offside call and Kolodynski also headed wide ahead of the match's conclusion, but it would have been harsh on the visitors to have conceded late on and the right outcome was probably achieved in the end.
