Ten-man Blades blow lead twice at Coventry
Sheffield United went temporarily top of the EFL Championship after a 2-2 draw away to Coventry City despite twice surrendering the lead and also going down to 10 men.
Chris Wilder's side moved one point ahead of Sunderland ahead the day's later matches, but were back in second after the Black Cats also drew 1-1 with Millwall, a point enough to return them to the summit on goal difference.
Tyrese Campbell put the Blades one up after 13 minutes, but Coventry forward Norman Bassette equalised nine minutes later.
Crystal Palace loanee Jesurun Rak-Sakyi, who provided the assist for Campbell's opener, had the visitors back in front on 34 minutes, having been set up by former Coventry man Gustavo Hamer.
But then came the game-defining incident, with Anel Ahmedhodzic sent off in the 44th minute after grabbing Bassette by his neck and pushing him to the ground.
Tempers flared into half-time, but it was the home side who piled on the pressure in the second half.
The managerless Sky Blues got their reward 10 minutes from time through Bobby Thomas, meaning that they have now come back from losing positions to draw in back-to-back matches, and sit 16th on the table.
Elsewhere, Burnley went third after a second straight 1-0 victory as it beat Bristol City on the road.
Jaidon Anthony scored the only goal of the game, although the home side created plenty of pressure and saw a penalty claim denied in the second half.
Scott Parker's side, nevertheless, kept its fourth clean sheet in five to get back in the hunt for the top two.
Sheffield Wednesday and Cardiff City shared the points in a 1-1 draw at Hillsborough that did neither side many favours in their aims to climb clear of the relegation scrap.
Both goals came within two first-half minutes, with Ollie Tanner getting the visitors ahead from a Callum Robinson rebound in the 34th minute.
The lead didn't last long though, with Di'Shon Bernard on hand to scramble home and restore parity almost straight away.
The result leaves Wednesday in 14th, four points above the bottom three, while Cardiff is 19th and just a point above third-bottom Luton Town.
