England v India: Eoin Morgan states that Jason Roy is "preparing" to play in crunch clash

England's campaign has gone off track since destructive opener Roy injured his hamstring, losing two of the three games he has missed to put their semi-final hopes on a knife edge.

"Jason is preparing to play tomorrow [Sunday]," Morgan told his pre-match press conference.

"Provided he gets through today's practice and tomorrow morning unscathed, we think he might be fit to play."

Morgan added, though, that the Surrey man will not play if there is deemed to be a long-term risk associated with doing so.

"It depends on the significance of the risk," he said. "If it's going to rule him out long-term, absolutely not. If it's a couple of weeks, yes."

There are also fitness concerns over strike bowler Jofra Archer who is managing a side strain.

"He didn't bowl yesterday," Morgan said ahead of Sunday's game. "We're going to see how he comes through today. It's the same thing he's been playing with for the last three games. Again, the same thing applies.

"If it's a long-term risk, no, if it's a short term-risk, yes."

England v India: Talking Points

Sunday June 30 - Edgbaston, 1030 BST

England head into their penultimate World Cup group game vulnerable after back-to-back defeats against Sri Lanka and Australia.

That their opponents are India, the side who have just leapfrogged them on top of the world rankings, only increases the potential for drama. Here, Rory Dollard assesses the talking points.

1. England fit for purpose?

England have two crucial decisions to make, over opener Jason Roy's hamstring and paceman Jofra Archer's nagging side problem. One has been sorely missed during a three-game absence and the other is the team's leading wicket-taker. Captain Eoin Morgan has hinted selection may have to be a judgement call, with an element of risk lingering over both men. The verdict they reach, and how successful it proves, promises to be critical to the result.

2. Home or away?

England have found to their displeasure that home advantage at a World Cup does not extend to pitches - which have been slower and more bowler-friendly than they like - and this clash is set to feel like a fully-fledged away game. Birmingham's large British Asian community always makes itself heard when India are in town and with a few secondary ticket sales factored in, the majority of supporters at Edgbaston will be pulling for Virat Kohli's men. Already in a tight spot, how will England react to this extra factor?

3. Jonny be good?

Jonny Bairstow is a player who seems to thrive on adversity, churning out some of his best knocks when he feels under pressure or believes he is being challenged in a new or unfamiliar position. A tetchy media appearance following defeat to Australia, during which he suggested some pundits were willing the team to fail, hinted that he was working himself into a siege mentality that could yet pay dividends, even if former England captain Michael Vaughan did not see it that way. His battling century in Colombo last winter, one game after being left out of the Test side, was one of his best ever and how England need him to deliver another statement here.

4. In a spin

At the start of the tournament England found themselves confounded by spin, with South Africa and Pakistan both reaping the rewards of opening up with a leg-break bowler. The response to this apparent weakness was emphatic against Afghanistan, Morgan leading the way as the world's premier white-ball spinner, Rashid Khan, conceded eye-watering figures of 9-0-110-0. On a pitch that can offer big turn, Yuvzendra Chahal (10 World Cup wickets at 24.10) and Kuldeep Yadav, who took six for 25 in his first outing against England, will surely re-examine the theory.

5. Orange is the new blue

India will be wearing a brand new shirt for the game, part of the sport's recent embrace of away kits. Instead of their traditional light blue, which clashes with England's retro effort, India will be wearing a large splash of orange balanced by dark blue on the front and collar. Kohli has already offered his seal of approval, awarding it an eight out of 10. "I really like it, the contrast is nice. It's a nice change for one game", he said.
