Ireland international Tadhg Beirne is doubtful for the upcoming Six Nations tournament following an ankle injury.
The 27-year-old sustained the blow during the 11th minute of the recently concluded Heineken Champions Cup game between Munster and Saracens and was stretchered off the field with a twisted ankle.
Beirne made his Ireland debut in 2018 against Australia in Melbourne and has gone on to play 13 Tests. He was also part of Ireland's recently concluded World Cup campaign in Japan.
Apart from Beirne's injury, Munster also suffered two more setbacks with as prop John Ryan suffered a calf strain while Andrew Conway is set to undergo a return to play protocols after suffering a head injury in the second half of the game at Allianz Park.
Munster skipper Peter O'Mahony will continue to undergo rehabilitation after withdrawing from the game with a groin strain.
Meanwhile, Ireland head coach Andy Farrell has confirmed a 45-man squad that will participate in 24-hour mid-season stocktake at IRFU's High-Performance Centre.
Ireland will kick-start their Six Nations 2020 campaign with a clash against Scotland at Aviva Stadium in Dublin on 1st February.
