Ronan Curtis scored in the final seconds to earn League Two leaders Port Vale a 1-1 draw at Cheltenham.

The home side had led through George Miller’s 53rd-minute strike, but substitute Curtis fired an unstoppable shot into the top right corner to keep Darren Moore’s side top of the table.

After a cagey first half, the deadlock was broken by Miller’s fourth goal of the season.

Sam Stubbs’ header from Luke Young’s corner was turned onto the bar by Connor Ripley before Arkell Jude-Boyd’s follow-up was cleared off the line, but Miller pounced from close range.

Both sides struggled for cohesion during the opening 45 minutes, with Nathan Smith heading Tom Sang’s cross wide in the 19th minute.

Sang reached a ball into the box ahead of goalkeeper Joe Day, but Stubbs made a sliding block in the box to clear a minute later.

Joel Colwill’s diving header grazed the post for the home side just before the break.

Miller’s opening goal sparked an improvement from Vale, who were close to levelling through Rico Richards, but Day blocked well in the 66th minute.

Cheltenham looked to have held out, but Curtis smashed in after good work from Ruari Paton on the left.
