Youssef Chermiti faces a long recovery from anterior cruciate ligament damage sustained shortly after Rangers turned down an offer for the striker.
The 22-year-old Portuguese was injured during Sunday’s 2-1 home defeat to Hibernian as he collided with advertising boards following a jarring challenge.
A club announcement via social media states Chermiti “will be out of action for a significant period of time”.
He moved to Ibrox from Everton in September 2025, reportedly becoming Rangers’ most expensive purchase since Tore Andre Flo in 2000.
Capped at under-21 level by Portugal, the centre forward has made 43 Rangers appearances, 30 of them starts, scoring 15 goals.
Asked about reports that Turkish champions Galatasaray had made an approach for Chermiti, Rangers manager Derek McInnes told BBC Scotland prior to kick-off: “I’m led to believe the club’s valuation of the player hasn’t been met.
“It’s no surprise that he’s a player who’s got a big (price) tag on him and he’s got high potential, but thankfully he’s our player and that will continue to be the case.
“We’re trying to build a team here at the minute and we’re trying to still bring additions to the team that helps us add to the good players that we’ve got, including Youssef.
“So it’s not something we would encourage at any point.”
