Wales and Ospreys star Justin Tipuric is set for a three-month break from rugby following the concussion he suffered against Italy.
The injury occurred during the recent Six Nations game in Cardiff and Ospreys have on Monday given a medical update on the flanker.
"Justin is recovering well following the concussion suffered playing for Wales against Italy three weeks ago, but in the light of his symptoms the specialist advice is that it is in his best interests to take his time returning," read the news on their official website.
"A prolonged three-month period of recovery rules him out of the rest of the season for the Ospreys and the Wales tour to New Zealand. The focus for Justin will be on getting healthy and fit, ready for pre-season."
In a further blow for the PRO12 region, they will also be without props Ma'afu Fia (toe surgery) and Paul James (eye surgery) and centre JJ Engelbrecht (angle surgery) for the rest of the season.
