League Two Wrap: Top two draw, Oxford held
League Two's leading pair of Chesterfield and Scunthorpe United refused to yield to each other in a 1-1 draw on Saturday.
Leaders Chesterfield went into the game at Glanford Park with a three-point buffer over their hosts, and left with that gap intact thanks to Eoin Doyle's penalty in first-half stoppage time, which cancelled out Sam Winnall's 15th-minute opener for Scunthorpe.
Third-placed Oxford United missed out on the chance to make up ground on the top two as they were held to a 1-1 draw at struggling Bristol Rovers.
James Constable put Oxford ahead after 10 minutes, but the visitors were denied a win that would have put them second when John-Joe O'Toole struck six minutes from time.
Despite the disappointment, managerless Oxford can take comfort from the fact they have now gone 16 League Two away matches without defeat.
Rochdale and Burton Albion remain hot on their heels following respective wins over AFC Wimbledon and Morecambe.

Bottom club Northampton Town's woes continued as they went down 2-0 at home to Plymouth Argyle, for whom Reuben Reid and Lewis Alessandra struck, while seventh-placed Southend United were beaten 2-1 at Mansfield Town.
