The 32-year-old has played every minute of the league campaign for the Reds this season, but has been doing so with an injury for "quite some time" according to coach Mike MarshLiverpool captain Steven Gerrard will "likely" require surgery on his shoulder during the summer, according to first-team coach Mike Marsh.
The 32-year-old has been playing through the pain barrier for some time, according to Marsh, after completing every minute of the Reds' Premier League season thus far - but Gerrard is now expected to miss England's friendly double-header against Republic of Ireland on May 29 and Brazil in Rio de Janeiro four days later.
Marsh also revealed that the injury is similar to that of Liverpool teammate Joe Allen, who went under the knife to prematurely end his season.
"It's looking more and more likely that he might require surgery," Marsh told the club's official website. "He has been playing with a shoulder injury for quite a while now. If it gets to the stage where he gets any worse, we'll try to find the right time for him to get it fixed properly.
"It's not ideal timing, it's going to take quite a while for him to heal. It's a funny injury - it's pretty similar to Joe Allen.
"If it needs repairing, it needs repairing and when he's back fit, he's back fit. There's not much we can do about it."
Gerrard has scored nine Premier League goals this season, plus a further nine assists, as Liverpool looks for a Europa League qualification spot before the end of the campaign.
