Leinster and Ireland backrow Jordi Murphy is expected to be sidelined for up to 12 weeks having undergone surgery on a shoulder injury and looks set to miss the November Tests against South Africa, Georgia and Australia.
Ahead of Leinster’s opening Pro12 fixture away to Glasgow on Saturday, the province issued an injury update, and said that Murphy had had surgery on the injury, which had caused him discomfort at the end of last season.
With Ireland lined up to face the Springboks on 8 November, Georgia on 16 November and Australia on 22 November, Murphy would appear to be ruled out, barring a quicker-than-expected recovery.
Dave Kearney and Richardt Strauss - suffering from long term knee and hamstring injuries, respectively - continue to be monitored on a daily basis but both players are recovering well and are on schedule for a return to fitness within the next few months.
Flanker Dan Leavy suffered a medial strain to his right knee in last weekend’s pre-season friendly defeat to Ulster and will be out for between 6-8 weeks.
Elsewhere, Connacht captain John Muldoon, prop Ronan Loughney and forward Aly Muldowney all returned to full training at the Sportsground on Monday and are expected to be available for selection this week, the Western province said.
Unavailable for Connacht season opener against the Dragons is new centre Shane O'Leary who picked up a knock to his quad in training last week.
The 21-year-old Cork man, who joined Connacht during the summer from FC Grenoble, should regain running later in the week and will be assessed ahead of the round two fixture away to Edinburgh.
Also unavailable for another week is winger Matt Healy, who sustained a hand fracture in Connacht's pre-season game away to Clermont Auvergne last month.
Healy joins Tiernan O'Halloran (knee), Mils Muliaina (elbow), Andrew Browne (knee), Jason Harris-Wright (shoulder) and Mata Fifita (shoulder) on the injury list.
