League One round-up: Chesterfield relegated, Fleetwood chasing automatic promotion
Fleetwood kept the heat on Bolton in the League One automatic promotion race with a 1-0 home win against play-off chasing Millwall.
Defender Ben Davies struck his first senior goal for Fleetwood in first-half stoppage time and that was enough to lift them to within a point of second-placed Bolton, who play local rivals Bury at home on Tuesday.
Sheffield United, crowned champions on Saturday after Bolton's defeat at Oldham, celebrated in style with a 3-0 win in a lunchtime kick-off at Bramall Lane against Bradford, who failed to book their play-off spot.
The Blades put the Bantams to the sword with a brace from Leon Clarke and Billy Sharp's 27th goal of the season.
Scunthorpe sealed their play-off place and stayed in the hunt for automatic promotion with a 3-1 home win against Chesterfield, whose relegation was confirmed.
Scunthorpe were 2-0 up at half-time thanks to Paul McGinn's own goal and a header from Ivan Toney, who added his second in the 73rd minute.
Tom Anderson headed a stoppage-time consolation for Chesterfield, but their fate was already sealed.
Southend's hopes of a top-six finish were dealt a blow as they lost 2-1 at home to MK Dons.
Joe Walsh and Ben Reeves scored for the Dons in the second half, with Simon Cox's penalty deep in stoppage time - for George Baldock's foul on Marc-Antoine Fortune - too little to late for Southend.
Rochdale kept their outside hopes of a top-six finish alive with a 2-0 home win against already-relegated Coventry, thanks to headers in either half from striker Ian Henderson.
Bristol Rovers also retained faint hopes of a top-six finish as they beat Oldham - who are not yet mathematically safe - 1-0 at the Memorial Stadium, where Ellis Harrison scored midway through the second half.
Port Vale's own survival bid was dealt a blow as they lost 2-0 at Oxford, who scored in either half through Josh Ruffles and substitute Chris Maguire to leave the visitors in the bottom four.
Fellow relegation battlers Swindon remain a place and a point behind Vale after they went down 1-0 at Walsall, for whom Joe Edwards scored a late winner.

Jason Pearce's header and Ricky Holmes' free-kick put Charlton 2-0 up at half-time and Josh Magennis added a third early in the second period.
Shrewsbury edged further away from the drop zone following a 1-1 draw at nine-man Northampton.
Marc Richards headed Northampton in front with his 13th goal of the season, but home defender David Buchanan was sent off for his second bookable offence soon after the break.
Mat Sadler headed Shrewsbury level 10 minutes later and the Cobblers were reduced to nine men in the 90th minute when midfielder John-Joe O'Toole received his second yellow card.
Wimbledon were held to a goalless draw at home by mid-table rivals Peterborough.
