Connacht head coach Stuart Lancaster admits it's unclear whether Mack Hansen will play again this season.
The Ireland and Lions winger is recovering from surgery on his foot earlier this month, which is likely to rule him out of the Six Nations.
Hansen went under the knife after he suffered a re-occurrence of the injury while playing for Ireland in the November internationals.

Lancaster says his comeback will be a "relatively long process", but it's too early to put a timeline on the recovery.
