Wales lock Will Rowlands (31) will miss the Six Nations due to a shoulder problem, he said on Monday.
He suffered the injury during last month's 20-13 victory over Argentina in Cardiff.
"The shoulder is OK, it is frustrating, but it is just slow and steady," Rowlands told the BBC.
"Hopefully, I will be involved back in rugby in April time."
Wales play their first game of the Six Nations against Ireland on February 4.
That match will be the first for the team under Warren Gatland, Wales's most successful and longest-serving coach who started a second spell in charge this month after replacing Wayne Pivac.
