Skelly Alvero suffered an injury during training on Friday, as confirmed by SV Werder Bremen team doctor Dr. Georg Tsironis. The Werder loanee underwent an MRI on Friday afternoon, which revealed that the midfielder had suffered an injury to the acromioclavicular joint in his shoulder. Following discussions with the team doctor from Olympique Lyon, Alvero's parent club, the injury will be treated conservatively and the midfielder will not undergo surgery. The 21-year-old could therefore return before the end of the season.
