Surrey’s T20 Blast game against Sussex was abandoned after two fielders were taken to hospital by ambulance after they collided on the field.
Surrey players Rory Burns, 24, and Moises Henriques, 28, were hurt in the 19th over of Sussex’s innings.
Umpires Jeremy Lloyds and Alex Wharf immediately halted play to allow them to be given treatment by medical staff.
A stadium announcement at Arundel, made at about 16:30 BST, said both players were conscious and sitting up.
Three ambulances arrived on the outfield shortly after the collision and both players were taken away in the emergency vehicles about 45 minutes later.
BBC London’s cricket correspondent Mark Church described the incident as the worst he had seen in a cricket match.
He said both players tried to take the same catch, Australian all-rounder Henriques backpedalling from backward point with batsman Burns running in from the boundary.
“It was a horrible incident that nobody wants to see happen on a cricket field,” said Church, who has been covering the sport for about 15 years.
“Both players were looking into the sky, looking for the catch, and went straight into each other.
“The atmosphere in the ground was very quiet as the players received treatment. If you saw that in the street you would be very upset to see it. It was awful.”
Former England player Chris Adams, who played for Sussex and coached Surrey, said the decision to abandon the match was the correct one.
“Not one person in that ground showed displeasure at that decision, in fact there was a round of applause when it was abandoned,” he told BBC Sussex.
“Well done to the authorities, particularly the medical teams who were out there very, very swiftly.
“It was a sickening collision and they got absolutely brilliant treatment and attention.”
Henriques, who has played three Tests, six one-day internationals and four T20 internationals for Australia, joined Surrey in April as an overseas player for their T20 Blast campaign.
Surrey-born Burns, a left-handed batsman and occasional wicketkeeper, made his first-class debut for the county in 2012.
Sussex were 141 for 7 after 18.4 overs when the collision happened.
About 8,500 fans were watching the match, with Kevin Pietersen making his final appearance for Surrey before going to play in the Caribbean Premier League.
