England would be naive to play Jofra Archer during the World Cup – Eoin Morgan

Archer played a key role in securing the trophy for Morgan's men four years ago, topping the wicket charts and delivering the nail-biting super over in the Lord's final.

But the Barbados-born seamer has played just seven ODIs since that day, with a litany of fitness problems making him a regular in the treatment room while he has not featured competitively since the IPL in May.

He is scheduled to join up with England shortly as a reserve player - partially to oversee his continued rehabilitation from a stress fracture of the elbow and partially as a potential injury replacement if required.

Should one of England's chosen seamers go down during the lengthy trip around India, there is hope that Archer could step into the breach and play a part in the business end of the competition, but Morgan has urged caution over that idea.

"It's not something that I'm thinking would be a good idea," said Morgan, who is in India as an ICC World Cup ambassador. "Right here and now I don't know because he's not played and we don't know what he's capable of.

"Given the injury issue that he's had in recent times I think it would be naive of anybody to think just chuck him in whenever you can because we're either desperate or feel that you need an option.

"Obviously the feedback about when he's trained with the team has been that he's back bowling beautifully, but you would like to see that in a game, you would like to see that in a continuous performance."

Morgan's successor as skipper, Jos Buttler, offered no new clues about Archer's status.

"He's coming out soon. The plan is obviously to finish off the rehab stages of coming back from his injury," he said. "He's continuing to build up and rehab and that's a great place for him to be able to do that in and around the squad.

"Obviously if he builds up and everything then should the worst case happen (to another bowler) it's a conversation."
