Republic of Ireland boss Martin O'Neill may have to make do without Jeff Hendrick for Tuesday's meeting with Serbia as the midfielder is still a doubt.
Hendrick sat out the 1-1 draw in Georgia at the weekend due to a thigh problem and is said to have undergone further scans on Monday morning.
According to Sky Sports News, the Burnley ace - a key player for the Boys in Green at last summer's European Championship finals - is still touch and go on the eve of the crucial World Cup qualifying clash at the Aviva Stadium.
Ireland currently trail opponents Serbia by two points at the top of Group B with just three games left to play, having been held in Tbilisi last time out.
The rest of O'Neill's squad took part in training at Abbotstown earlier today.
