Allen has successful surgery
Leeds midfielder Paul Green has been preferred to Wigan's James McCarthy for the Republic of Ireland's crucial World Cup qualifier in Sweden.
Green, whose presence in the side has not always attracted the universal approval of fans and pundits, will partner Stoke's Glenn Whelan in the centre of the field at Stockholm's Friends Arena.
Manager Giovanni Trapattoni's team was otherwise as hinted at in training sessions this week, although the Italian, in naming his line-up, admitted a doubt over Hull winger Robbie Brady.
Brady is not injured but Trapattoni wants to make sure he is mentally ready for the Group C encounter before finalising his side. Millwall goalkeeper David Forde will make his first competitive start while Aston Villa's Ciaran Clark will partner John O'Shea in central defence.
West Brom striker Shane Long was selected alongside captain and record goalscorer Robbie Keane up front.
Trapattoni feels 29-year-old Green will offer more balance to his side than the attack-minded McCarthy as he looks to utilise the forward threat of players such as right-back Seamus Coleman.
Trapattoni said: "The situation is - away team, away game. I wish Coleman to go (forward). When he goes, we need protection. This result is very important and it is important we play our game.
"I saw his (Green's) last game in England. He he played very well. It is important we have protection in midfield. McCarthy also played very well but I couldn't ask him to stay in this position."
Trapattoni also challenged Brady, 21, to prove he is fired up for the contest.
He said: "I spoke with him. I said, 'Are you sure, are you okay?' He said, 'Yes'. I wish to push him. I liked him against Poland.
"I said he must repeat this game. He promised me after the training (he would) and I will speak again with him. It is not a big problem, only psychological. I push him."
Ireland are third in Group C a point behind Sweden, who in turn trail leaders Germany by three points.
Republic of Ireland team to face Sweden in World Cup Group C qualifier at Friends Arena, Stockholm: Forde, Coleman, O'Shea, Clark, Wilson, Brady, Green, Whelan, McClean, Keane, Long.
The 23-year-old Welshman has already been ruled out for the remainder of the current season but the operation has been declared a success.
Glen Driscoll, Liverpool's head of performance, told the club's official website on Thursday: "Joe Allen had surgery this morning, which went very well.
"It's going to be a relief for Joe that this has now happened for him. It has been quite a long-standing issue. He was repetitively subluxing, so his shoulder was coming out very easily and very often.
"It was a procedure that was very important. He should be fighting fit for the start of pre-season."
Allen has been troubled by the injury to his left shoulder since November last year, and he aggravated the problem in Saturday's 3-1 defeat at Southampton.
