Leinster head coach Leo Cullen says he is unsure as to the extent of the disruption the outbreak of coronavirus will have on the Pro 14 season.
The reigning champions are scheduled to travel to South Africa for a fortnight on 14 March, for their away games against the Cheetahs and the Southern Kings.
Cullen's side have won all 12 games in their domestic game, as well as all six of their Champions Cup encounters, the majority of the home matches being won by eye-watering margins.
Leinster host Glasgow on Friday in a repeat of last year's decider, with the South African trek looming into view afterwards.
However, the coronavirus outbreak, which has already forced the postponement of the Ireland-Italy Six Nations game, has thrown the South African fixtures into doubt.
Cullen admits the issue has created uncertainty, though he stresses that Leinster will do whatever the authorities decree and says their immediate focus is on Glasgow at the RDS.
"It creates a bit of uncertainty," the head coach told RTÉ Sport. "And uncertainty creates a lot of questions. And you're asking me questions I don't know the answer to. So, that what it creates.
"And we just need to crack on with what we're doing. I've no control over any of those things.
"We had the bit of uncertainty for our last home game against Cheetahs, and whether it would be postponed because of the storm.
"We'll just go with whatever the authorities tell us to do. At the moment, the South African trip is in the distance.
"For us, it's the here and the now. We've a big game here tomorrow against Glasgow, conference rivals as well. We also that recent history from the final last year as well. We know they're a top team and a well coached team. And we'll try to prepare the team well here this week.
"We've no game next week so we take a bit of a break next week. We can re-assess and make a plan for what's best going forward. We've a training week after that and then we're due to leave for South Africa on the day Ireland are due to play France. So, that (Ireland game) is still in situ there at the moment.
"Even in the game, you get all these little distractions. So, there's this big-piece distraction which we've no control over whatsoever."
Cullen made eight changes to his Leinster side for Friday's clash, with Hugo Keenan selected at full-back, Dave Kearney on the wing, while Joe Tomane replaces Conor O'Brien in the centre alongside Jimmy O'Brien.
