"Ben is ready to return to action following the neck injury he sustained at the end of September," said Ospreys head physio Chris Towers.
"We've been gradually building him back up into rugby and contact sessions over the last few weeks, and there have been no adverse effects, while he satisfied the necessary requirements in terms of fitness testing.
"In light of this, along with specialist opinion that he is now fit to play again, he has been made available for selection again from this week onwards."
The Ospreys are currently fifth in the Magners League table and return to action this weekend when they welcome Ulster to the Liberty Stadium.
