Arsenal goalkeeper Lukasz Fabianski is set to be sidelined for the rest of the season.
The Polish international damaged his shoulder earlier this term and he aggravated the problem during a warm-up ahead of their match with Manchester City.
Now Fabianski is having surgery which is set to sideline him for the remainder of the season.
"The doctors expect me to take a long break," Fabianski said.
"But we'll see if that will happen."
Countryman Wojciech Szczesny will now get the chance for an extended run in the first team, and he admits he indirectly caused the injury.
Speaking to sports.pl, he said: "I was warming Fabian up before the game with Manchester City and I took a very powerful shot.
"He made a beautiful save but also got an injury. I didn't do it on purpose, I was just doing my job.
"I feel stupid about it. I even told him it would have been better if he didn't save that shot. I take advantage of my team-mate's misfortunes."
