Wales captain Alun Wyn Jones black eye was allegedly caused after an altercation with a fellow squad member during training last week.
The Rugby Paper and Mail Online has reported that the most-capped player of all-time clashed with second-row partner Jake Ball in a heated exchange.
The damage done to Jones is clear to see in the video below.
Ball, who will move to Australia at the end of the season, isn’t involved in Wayne Pivac’s squad for the game against Ireland in Cardiff following the incident.
The altercation is said to have been played down by sources close to Wayne Pivac’s camp despite Alun Wyn Jones black eye.
The WRU were contacted for comment about the reports of the alleged altercation.

OTHER INFAMOUS BUST-UPS
Martin Johnson & Lewis Moody, 2004
Moody’s desire to impress on his return after injury in 2004 caused a flare-up with the then Tigers captain.
“It was my first session and I was extra keen, trying to do everything and hit everything,” Moody told The Sun.
“Tempers flared and ‘Johnno’ and I had a little coming together. He gave me a little dink and I gave him a little dink – but his hurt a lot more! It’s just typical training ground stuff. You need that friendly rivalry.”
The former England captain also famously came to blows with Tigers teammate Alesana Tuilagi when England faced Samoa at Twickenham.
