Wales flanker Dan Lydiate is recovering as expected after sustaining shoulder and hamstring injuries against England in May.
Lydiate captained Warren Gatland's men at Twickenham but was forced off in the first half and was subsequently ruled out of the summer tour to New Zealand.
"Dan is recovering well from surgery to reconstruct the shoulder ligaments he damaged against England," Ospreys medical performance manager Chris Towers said.
"In addition, Dan also injured his hamstring in the same match. He's recovering well on both fronts but still has some work to do.
"We'll be looking to up the ante through this next batch of pre-season with a view to being able to confirm a return to play date in the next few weeks."
James King, a second Wales and Ospreys back row, is also in rehabilitation after sustaining a neck injury in New Zealand.
"James is progressing well but we will continue to observe his recovery and progress over the coming weeks before we will be in a position to confidently predict when he will be available for selection," Towers said.
