Reading’s League One match against Port Vale was abandoned after hundreds of home fans invaded the pitch in protest against owner Dai Yongge.

Reading urged supporters to leave the pitch, but the game was called off when they refused.

“Every effort was made to restart the game but it became increasingly obvious that this would not be possible,” said an EFL spokesperson.

“We will now discuss the implications of this afternoon’s events with the clubs involved.”

Sell Before We Dai, a fan-led group urging Yongge to sell Reading, said the action was “just the start”.

“We shouldn’t be doing this. We should be enjoying the game with friends and family,” the group posted on X.

“This is just the start Dai. We are coming for you. So do yourself a favour and sell.”

Play was held up in the third minute when supporters threw tennis balls on to the pitch.

“We must reiterate to our supporters that entering or throwing items onto the pitch can put the fixture at risk of abandonment and can result in personal consequences including banning orders,” Reading wrote on X.

“We appreciate supporters’ frustrations. Please leave the field of play. The club will face serious sanctions if this does not take place.”

Last month fans protested at the Houses of Parliament against Yongge following sanctions imposed by the EFL, including a transfer embargo over an unpaid tax bill.

Reading have suffered a series of deductions totalling 16 points since November 2021, including four in August.

They are fourth from bottom of the table, three points from safety.

Bolton Wanderers’ League One game against Cheltenham Town was called off earlier on Saturday because of a medical emergency in the stadium.
