Ireland captain Rory Best must prove his fitness on Thursday in order to face Scotland in Saturday’s final RBS 6 Nations encounter.
Ireland’s most-capped hooker sat out Tuesday’s training with a tight calf in what assistant coach Richie Murphy deemed a precautionary move.
The 33-year-old Ulster front-rower is expected to come through in time for the Aviva Stadium clash, with Cian Healy and Eoin Reddan now also back in training.
Healy missed the 58-15 win over Italy with hamstring trouble while Reddan was sidelined with a calf problem, but both are now free to return to the squad to face Scotland.
“Rory Best sat out of training today,” said Ireland’s skills coach Murphy.
“He trained yesterday and came off. He was a little tight in the calf at the end of training.
“It was judged not to train him today and he should be ready to train on Thursday.”
