Ulster Rugby's Johann Muller faces month on sidelines
Ulster have suffered a major injury blow, with captain Johann Muller being ruled out for four to six weeks.
Muller sustained a torn calf muscle during last week's Pro12 victory over Cardiff Blues, and the South African will miss this month's Pro12 matches against the Scarlets, Edinburgh and Zebre.
There is, however, a chance that he could return for the home Heineken Cup clash against Benetton Treviso on December 7.
Meanwhile, the IRFU has received worrying reports that Donnacha Ryan visited Perpignan's training facility and watched their Top 14 win over Bordeaux on Saturday.
The Ireland head coach Joe Schmidt, however, had more pressing matters to deal with than a possible move abroad by the 29-year-old Munster and Irish lock.
Sidelined for 10 weeks with a knee injury, Ryan is out of contract at the end of the season and weighing up his options.
A host of players reported for duty at Carton House last night carrying injuries and Conor Murray was cited after an incident during Munster's win over Glasgow Warriors on Friday.
Schmidt is anxiously awaiting the outcome of the scrum-half's disciplinary hearing after it was confirmed that he and Glasgow replacement Niko Matawalu face possible sanction following separate incidents during a bad-tempered second half at Scotstoun.
Murray was involved in a 60th-minute incident on the try-line with the Fijian, when he appeared to lash out with his arm after denying his opponent a try.
Referee Ian Davies did refer the incident to the TMO to check whether the score had been completed, but Jim Yuille did not pick up on any foul play.
However, Glasgow referred the incident to citing commissioner Rob Flockhart, who last night deemed the incident worthy of investigation and cited the Munster player for 'foul play contrary to law 10.4 (a) striking with the elbow.'
Matawalu was cited for foul play contrary to law 10.4 (m) – act contrary to good sportsmanship.
