Keiren Westwood has been suffering from a rib injury
Republic of Ireland goalkeeper Keiren Westwood has been ruled out of the World Cup qualifiers against Moldova and Wales with a rib injury.
Sheffield Wednesday player Westwood, 32, withdrew from Martin O'Neill's squad on Monday.
With striker Kevin Doyle having retired because of concussion-related symptoms, the Republic squad has been cut to 30.
James McClean and Robbie Brady are suspended for the home game against Moldova on 6 October.
Two days later, O'Neill's squad will travel to Cardiff for the final Group D match against Wales on 9 October.
O'Neill named his initial squad on 26 September, including the uncapped Aston Villa striker Scott Hogan.
English-born Hogan, 25, who had been linked with the Republic for some time, was summoned to fill the gap left by the absence of Burnley forward Jonathan Walters, who has a knee injury.
Millwall forward Aiden O'Brien also receives a first senior international call-up.
James McCarthy, Wes Hoolahan and Harry Arter were included despite being injury concerns.
Walters' Burnley team-mate Jeff Hendrick returns after missing the games against Georgia and Serbia earlier this month with a thigh injury.
The defeat by Serbia dropped the Republic to third place in Group D and they will need to beat Moldova and earn an away win over Wales to keep alive any hope of qualification.
