The Ibrox midfielder has struggled with a persistent calf issue and has been told by a top London specialist he requires an operation next week – meaning he will play no part for Steve Clarke’s squad this summer.
Gerrard said: “Unfortunately it’s mixed news for Ryan and the bad news is he’s ruled out for the rest of the season, so you won’t see Ryan play for Rangers again this season.
“He’s also ruled out of the Euros this summer, which is bad news for him from a personal point of view and everyone connected with the Scottish game as I think he’s been phenomenal for the national team.
“He was very much looking forward to that so it’s sad news for him. But the good news is that we’ve found a solution and got to the bottom of the problem.
“All being well in terms of his rehab from the procedure that he will have next week, he should be due to return in pre-season at some stage.”
