Cooper set for spell on the sidelines
Cooper was forced off in the 22nd minute of Millwall's win at home to Birmingham City on Wednesday evening
The Ex Reading man sustained damage to the same shoulder in the reverse fixture at St. Andrew's back in November in a 0-0 draw.
However, Cooper then played the remaining 20 minutes of the game and Millwall were hoping that the operation could be put on hold until the end of the season and therefore he would only miss one game before returning to the side.
Gary Rowett has conceded that an operation is 'likely' and therefore Cooper may not feature for the rest of the campaign.
Speaking to the South London Press, Rowett said:
“We think he has dislocated the shoulder but in a slightly different way. He is seeing a specialist on Friday and looks very likely he'll have an operation.”
Zohore also out
The injuries are mounting up for the Lions and they received more bad news as Kenneth Zohore is set for a spell on the sidelines too.
Zohore arrived from West Bromwich Albion on loan initially until January 16th but this was extended until the end of the season.
The Dane suffered an injury on his first league start for Millwall in October and he did not return until January, after he suffered a calf problem in their 2-0 away win against Preston North End.
Gary Rowett said: "He is another one seeing a specialist. I believe he will probably be between four to eight weeks. There is some sort of damage to the ligament at the front of the ankle."
This is a big blow for Millwall, Jake Cooper and Kenneth Zohore have been regulars in the side recently. Alex Pearce could keep his place in the side when Wycombe Wanderers travel to The Den on Saturday after coming on for Cooper on Wednesday evening.
