Denly was down for 15 minutes after twisting his knee while playing football
Joe Denly has been ruled out of England's second one-day international game against Australia on Sunday after undergoing a scan on his injured knee.
The Kent batsman suffered the injury while playing football during a training session at The Oval ahead of the first limited overs game on Friday.
An England and Wales Cricket Board statement read: "Joe has suffered a small sprain to the left knee.
"Further assessment of the scans have revealed no major structural damage."
Denly, 23, caught his studs in the turf and damaged his knee when he collided with Owais Shah.
The clash left him injured on the ground for 15 minutes before he was helped off by physio Kirk Russell and England's head of security Reg Dickason.
England captain Andrew Strauss says the team may now consider banning football as part of their warm-up.
"The reason we play football is that it's something the guys enjoy and it gets the blood flowing," said Strauss.
"We feel, or certainly had felt, if it's played sensibly the chance of getting injured is very slight. If people are going to get injured playing it, we've got to look at it.
"Up to this stage we have never had anyone missing cricket through playing it. You'd like to think players would be sensible enough in the warm-up not to take it too far.
"When we do play football we have a no tackling rule. Any injury is not ideal, you want a full squad to choose from."
England's tradition of playing football before matches has been criticised in the past.
James Anderson twisted his ankle during an end-of-day warm-down at Wellington in March 2008 and Ian Bell turned his right ankle in the indoor nets ahead of this summer's third Test at Edgbaston.
However, England's Twenty20 captain Paul Collingwood was not prepared to let his bowlers run over a damp patch of ground in the controversially abandoned second international at Old Trafford on Tuesday.
Denly top-scored with 67 on his England debut against Ireland in August before being dismissed for a first-ball duck in the abandoned first Twenty20 international against Australia, also at Old Trafford.
