Wayne Rooney or Frank Lampard will captain England in their next two games unless Ashley Cole agrees to lead the side in recognition of his 100th cap.
Steven Gerrard misses the games
against Republic of Ireland and Brazil with a shoulder injury.
Ireland's return to Wembley
England have not hosted the Republic of Ireland at Wembley since the sides met in a European Championship qualifier in March 1991. Arsenal right-back Lee Dixon opened the scoring with his only international goal, before his former team-mate Niall Quinn equalised for the away side
"Frank Lampard and Wayne Rooney are captains-elect," said England manager Roy Hodgson, who revealed that Cole had been keen to "stay in the shadows".
Uncapped Reading keeper Alex McCarthy, 23, has received his first call-up.
England host the Irish at Wembley on 29 May in their first meeting there since a European Championship qualifier in March 1991.
Hodgson's men will then travel to Rio de Janeiro to face five-time World Cup winners Brazil on 2 June at the iconic Maracana Stadium, which
recently reopened after a three-year renovation.
The stadium, where a record 200,000 people watched the 1950 World Cup final between Brazil and Uruguay, has been refurbished ahead of next year's World Cup.
Chelsea left-back Cole, 32, will be presented with the
100th cap he won against Brazil in February
before the clash against Giovanni Trapattoni's Republic of Ireland side.
Roy Hodgson could appoint Wayne Rooney as captain for the friendlies
Hodgson said Cole could skipper the side at Wembley to mark the occasion but added he may be a reluctant leader.
"We haven't named the captains before because we usually have Steven Gerrard available," said Hodgson.
"I will speak to Ashley Cole. Most players who earn 100 caps are given the captaincy, but last time I spoke to Ashley he was more than happy to stay in the shadows. I will speak to him again."
Should Lampard captain England, it would cap a marvellous fortnight for the midfielder, who
signed a new one-year deal at Chelsea
shortly before the England squad was announced. The contract extension came after the 34-year-old helped the Blues win the Europa League and became their all-time record goalscorer.

Hodgson insists former England Under-21 international McCarthy deserves his call-up after impressing in his 13 appearances for the Royals this season.
"We have not had a lot of chances to use Jack Butland, who came with us to the Euros, in the last few months because the Under-21s are preparing for the important tournament in Israel," said Hodgson.
"We have had a very good look at Celtic's Fraser Forster, and having seen Alex McCarthy, and read reports, it will be a good chance to have a look at him. He deserves it because he has been playing well."
West Ham striker Andy Carroll, 24, has been recalled for the first time since October's World Cup qualifier in Poland, where he was an unused substitute.
Fellow forward Rooney, 27, was dropped for Sir Alex Ferguson's final game at Old Trafford after
asking to leave Manchester United.
Hodgson is unable to call on Rooney's Manchester United team-mate Rio Ferdinand. The 34-year-old defender
announced his international retirement on Wednesday.
