Ospreys wing Hanno Dirksen is to miss the start of the season after suffering a setback in his recovery from knee surgery.
The 22-year-old underwent a cartilage operation last November and had been expected to be fit for the new campaign, but Ospreys head physio Chris Towers confirmed Dirksen's recovery is taking longer than expected.
He said: "Hanno is behind where we originally predicted he would be at this stage after suffering complications that were beyond our control and which now appear to be remedied. Due to those setbacks he is only just starting on the rehab process during the pre-season period."
He added: "He is coping well but it will be a while yet until we will see him on the field training with the rest of the squad and we will update on an expected return time when appropriate."
