Carbery appeared to get his leg caught under a ruck in the 50th minute and received medical treatment on the pitch.
The Munsterman – clearly disconsolate – was apparently unable or unwilling to walk off and was eventually driven off by the medical cart.
"That is a real worry for Ireland"

Joe Schmidt – who returned from New Zealand following a family bereavement – will be left with an anxious wait for news on the 23-year-old.
If significantly injured, Carbery, who was playing his 19th Test for Ireland, will have a number of players bidding to replace him.
Carbery, Byrne and Sexton are the three flyhalves included in the current Ireland camp. If Carbery were to be ruled out, Billy Burns, Tyler Bleyendaal and JJ Hanrahan could all potentially benefit with a call-up to the Rugby World Cup training squad.
