Both Duffy and Keogh likely to miss Republic's crunch fixtures
Republic of Ireland boss Mick McCarthy could be without first-choice central defensive pairing Shane Duffy and Richard Keogh for next month's Euro 2020 double-header against Georgia and Switzerland.
Brighton's Duffy is expected to be sidelined for several weeks by a calf injury picked up during Wednesday evening's 3-1 Carabao Cup defeat by Aston Villa.
Manager Graham Potter said: "Shane is going for a scan, so we will see the extent of that. It looks like it is going to be weeks rather than days with him."
Derby defender Keogh will certainly miss the two games after being ruled out for much of the rest of the season with a knee injury suffered in a car accident.
A club statement released by the Rams yesterday afternoon said: "As a club, we cannot, and do not, condone the actions of a small group of players on Tuesday evening.
"The players were out as part of a team-building dinner and while the majority of them acted responsibly, a small group, including Richard Keogh, continued drinking into the night.
"As a result of an alcohol-related incident, Keogh has sustained a serious knee injury."
The Republic play Georgia in Tbilisi on October 12 and the Swiss in Geneva three days later.
McCarthy's men currently sit top of Group D by two points ahead of Denmark and three clear of Switzerland, who have played a game fewer.
