There's concern over Jordan Larmour's fitness less than a fortnight from the start of Ireland's Six Nations campaign.

Leinster have confirmed that the versatile back sustained a "low-grade foot injury" in Saturday's Heineken Champions Cup win over Benetton in Treviso.

Larmour will be assessed by the IRFU's medical team, with 19 Leinster players joining Andy Farrell's Ireland squad for a training camp in Portugal ahead of the game with Scotland on Saturday-week.

The 22-year old played 71-minutes of Leinster's 18-0 win at the Stadio di Monigo that maintained their 100 per cent record in Pool 1 and with it secured a home quarter-final with troubled Saracens.

Larmour was replaced by Rob Kearney on the day, but with no Kearney in Farrell's squad, he is expected to be Ireland's first-choice full-back come the visit of Gregor Townsend's side to the Aviva Stadium.

Leinster's only other injury concern arising from their trip to Italy was a neck injury sustained by prop Ed Byrne.

The loosehead will undergo a period of rehabilitation as a result.
