Fast bowler Jofra Archer trained with England on Tuesday, raising hopes he could still travel to the World Cup as a reserve to the frontline squad.
Archer, 28, has missed the entire home summer with a stress fracture in his right elbow.
He was not considered fit enough for a place in the 15-man World Cup squad, but could be one of three reserves.
England must finalise their party for the tournament in India in October and November by 28 September.
Archer famously bowled the super over in the thrilling 2019 final when England lifted the trophy for the first time by defeating New Zealand.
His career has been hugely hampered by injuries since then. Though he made an England comeback earlier this year on the limited-overs tours of South Africa and Bangladesh, the latest elbow injury robbed the Sussex man of the opportunity to play in the Ashes.
Archer bowled in the nets at The Oval on Tuesday as England trained before the third one-day international against New Zealand on Wednesday.
Speaking when an initial World Cup squad was announced in August, selector Luke Wright said a best-case scenario would be for Archer to travel to India as a reserve, with the potential to play a part in the second half of the tournament.
"There has got to be a duty of care with Jof," said Wright. "We know how desperate we all are to have him, but we've also got to get it right for him.
"He's been very unfortunate with these injuries, so we do have to get it right."
In 2019, Barbados-born Archer had only just qualified to play for England and his inclusion in the World Cup squad came at the expense of David Willey.
Willey has been named in the World Cup party this time around and said that Archer looks "in a good place".
"I don't know where he's at fitness wise but he's bowling good wheels out there today," said Willey.
"Everyone knows how good is he is, what he's capable of and how he can impact games. So to have him close or not far away from being fit is obviously fantastic news."
'Nothing will ever be as bad as that'
Willey, meanwhile, said another World Cup omission would be "tough to take".
While Willey is in the squad named for the tournament, England can still make changes right up until 28 September.
"Until you're on that flight out there you can't rest on your laurels," the Northants bowler said.
"Of course it can change, they've not got to finalise until the end of the month. It's out of my control. It was out of my control in 2019.
"I'd have given my left arm to be a part of the last World Cup. Anything that happens to me in cricket now is never going to be as bad as that."
When asked what he brings to the squad, Willey emphasised his physical durability.
"Call me a donkey if you want, but to take a donkey out to what could be a tough trip, you just might need a donkey," he said.
"Staying fit is probably an asset to the group, with guys who sometimes struggle with niggles and things. They keep going, donkeys, don't they?"
England's opening game of the World Cup is against New Zealand on 5 October.
