Substitute Cauley Woodrow snatched an equaliser in the final seconds of added time as Luton drew 1-1 at Crystal Palace to hand the Hatters a crucial point in their relegation battle.

Jean-Philippe Mateta’s early opener at Selhurst Park looked to be the winner until Woodrow headed home, extending the Eagles’ Premier League-leading tally of late goals conceded in the process.

Sunny Singh Gill made history as the first British South Asian to referee a Premier League match, and was spotted signing autographs as he waited in the tunnel ahead of the second half.

The result draws Luton within three points of safety, while Palace will be ruing a huge missed opportunity to put more breathing room between themselves and the drop zone.

Singh Gill’s decision-making was tested early, when Palace protested for what they felt was a Teden Mengi handball, but the ex-prison officer – who comes from a refereeing family – waved play on.

Luton’s brightest spell of the opening period came when the Hatters won an early corner and Palace were only able to half-clear, the ball pinging around the 18-yard box where Luton came closest through a nodded effort from Ross Barkley, who needed treatment for a nose bleed after colliding with Joel Ward.

Mateta rolled an effort at Thomas Kaminski during the hosts’ first real break into Luton’s final third, not long before the Eagles took an 11th-minute lead through the Frenchman.

Mateta’s fifth league goal of the campaign followed some good work from January signing Daniel Munoz, who was able to latch on to Alfie Doughty’s loose back pass and find his team-mate just inside the six-yard box, where he opened the scoring with a backwards flick.

The Hatters had a handful of chances to reply, but it was the Eagles who applied more pressure as Ward, Jefferson Lerma and Mateta all misdirected efforts.

Singh Gill issued his first Premier League booking to Issa Kabore, who took down Lerma with a reckless challenge in the 27th minute, and showed his second yellow to Eberechi Eze for a pull on Reece Burke’s shirt.

Palace, who managed to keep the in-form Carlton Morris quiet throughout the first half, had a chance to double their lead before the break when another back pass – this time from Reece Burke – allowed Mateta to pounce and round Kaminski, but he found himself at too tight an angle and fired into the side-netting.

Eze threatened twice before the hour mark, while Luton’s best early chance after the break came via Chiedozie Ogbene, who directed a header wide of Sam Johnstone’s left post from six yards out.

Morris finally had a crack, directing a sharp volley straight at Johnstone before Daiki Hashioka sent his effort over the bar.

It was nevertheless an encouraging spell for the Hatters, who entered the afternoon having scored more goals in the final 15 minutes than every Premier League side bar Liverpool, Manchester City and Arsenal – while the Eagles had conceded the most in that same period.

Yet it was the Eagles who had the first big chance in the final 10 minutes of normal time through an audacious effort from Eze, who launched the ball from inside the centre circle that the scrambling Kaminski could not have stopped, but to his relief skimmed just over the crossbar.

The majority of the chances in six minutes of added time went the hosts’ way – including a crossbar-clipping effort from Odsonne Edouard – but it was Woodrow who made his count when he guided in ex-Eagle Andros Townsend’s delivery to stun Selhurst Park.

Bolton’s League One clash with Cheltenham was abandoned after 29 minutes due to a medical emergency in the crowd.

Referee Sunny Singh Gill took the players off the field just after 3.30pm as medical staff went to help the supporter.

The match was officially abandoned 30 minutes later.

Bolton said the fan had suffered a suspected cardiac arrest and was taken to hospital.

A club statement read: “A supporter in the East Stand suffered a suspected cardiac arrest around 30 minutes into the game at the Toughsheet Community Stadium.

“The man was treated by medical staff and paramedics at the scene, while the two teams were taken off the pitch.

“Following sustained attempts to revive the patient, he was taken to the first-aid room at the stadium and the match was abandoned shortly after 4pm.

“The supporter was subsequently taken to hospital and the thoughts of everyone at Bolton Wanderers are with him and his family.

“An update on the supporter’s condition will follow.

“Details regarding a new date and ticket refunds/arrangements for the fixture will be released in due course.”

Cheltenham added: “Today’s fixture against Bolton Wanderers has been abandoned due to a medical emergency in the crowd.

“The thoughts of everyone at Cheltenham Town Football Club are with the individual involved and their loved ones at this time.”

The game was still goalless when play was halted. Kyle Dempsey had fired over for Bolton at one end while Cheltenham’s George Lloyd was denied by home goalkeeper Nathan Baxter.

Bolton ended the day still two points off the top of the table after leaders Portsmouth suffered a surprise home defeat, while Cheltenham remained three points from safety.
