Scotland's Johnnie Beattie and Sean Lamont will miss the Six Nations match against Wales on Saturday after being injured in the defeat by France.
Flanker Beattie damaged his right ankle and wing Lamont injured ligaments in his right knee during the 17-19 loss.
"In addition, prop Ryan Grant has a hip/abdomen injury which will require further assessment," said Scotland team doctor James Robson.
"He will undergo MRI imaging on Monday."
The game against France at Murrayfield has also resulted in seven other Scotland players needing treatment, although they are not considered serious at present.
