Alastair Cook had become "drained" as England Test captain, says England's director of cricket Andrew Strauss.
Cook stepped down on Monday after a record 59 matches in charge.
"He was getting drained by the relentlessness of being England captain," Strauss told the BBC's sports editor Dan Roan.
Strauss added that vice-captain Joe Root would be a strong candidate to take over but refused "to rule anyone in or out of the role".
Boxing
Anthony Joshua will beat Wladimir Klitschko in their heavyweight title bout at Wembley on 29 April, says former world champion Lennox Lewis.
Joshua, 27, will defend his IBF title for the third time, with the WBA belt vacated by Tyson Fury also on the line.
Klitschko, 40, lost for the first time in 11 years against Fury in 2015 - losing the IBF, WBO and WBA titles.
"I think it's perfect timing," Lewis told BBC Sport. "After a loss, there's a notch on Klitschko's armour."
Lewis, who retired in 2004 with 41 wins from 44 fights, believes unbeaten Joshua is "focused" and remains keen to prove himself after winning his title from American Charles Martin inside two rounds in April 2016.
"He got a belt given to him," Lewis added. "He didn't really earn it. So this is his time to earn that belt from the champion who had it."

Cook resigns as England Test captain
"Alastair Cook has been a fantastic England captain. Today we want to celebrate that and then turn our attention to his replacement.
"Alastair made the decision the right way and took his time and came out with a decision which is for the good of the team.
"He has been the longest-serving captain and has done it when the team has been under enormous scrutiny and often in quite turbulent times.
"All the players are supportive of him because of his drive, character and empathy because he can appreciate when others have had tough times, And he really cared about his team-mates, which is why he will be remembered fondly by all those who played with him."

Canada's Denis Shapovalov has been fined $7,000 (£5627.00) after hitting the umpire in the face with a ball during his Davis Cup match against Kyle Edmund.
The breakdown of the fine is as follows:
$2k (for the default)
$5k (for unsportsmanlike conduct. The maximum of $10k would only apply if it had been intentional).
The 17-year-old said he was "incredibly ashamed and embarrassed" after striking French umpire Arnaud Gabas in the eye - a default followed.
"Luckily he was OK but obviously it's unacceptable behaviour from me," said the Wimbledon junior champion.
"I just feel awful for letting my team down, for letting my country down, for acting in a way that I would never want to act."

Manchester City have no intention of selling Sergio Aguero this summer, despite the striker being left out of the team for the past two matches.
The 28-year-old signed a contract extension earlier this season, meaning he has three years left on his deal.

"In these [next] three months I have to help the club and then they will decide if I have a place here or not."
Despite Aguero expecting a decision to be made in the summer, senior City figures indicated on Sunday that they do not expect to sell the player.
