Royals goalkeeper Alex McCarthy underwent successful shoulder surgery earlier this week.
The 'keeper, who turned 23 on Monday, underwent the operation in London after picking up the injury in the very last minute of our Barclay Premier League draw at QPR last month.
Head of Sports Medicine Luke Anthony recalled the process behind the surgery, saying, "We had an encouraging MRI scan on the Monday after the QPR game, then we saw a shoulder specialist the following day and he was also positive that Alex should be able to recover with a conservative rehab programme. But it soon became clear that the structural damage wasn't going to improve without surgery, so we saw another consulant late last week and then on Monday Alex successfully had his labrum tissue repaired.
"Understandably supporters will ask how long Alex will be out, and it's difficult to put a time frame on his return. The most important thing is for Alex to make a full recovery and return in optimal condition. If that allows him to return before the end of the season then that is something we will try for."
