Giovanni Trapattoni will be waiting for positive medical news from Old Trafford after a first-half knock to John O'Shea ended his afternoon prematurely, writes Daniel McDonnell.
The Waterford man -- who was deputising at left-full for the injured Patrice Evra yesterday -- required treatment and was replaced at the interval by Jonny Evans.
Trapattoni will be hoping that it was just a precautionary measure to withdraw O'Shea, as he desperately needs the 30-year-old for the Euro 2012 qualifier with Macedonia on June 4.
In the absence of the suspended Richard Dunne, the Irish manager intends to use the experienced Manchester United man in the heart of the back four for the tricky trip to Skopje.
The 72-year-old has a number of injury concerns in that department, with Sean St Ledger, Darren O'Dea and also Ciaran Clark all having question marks hanging over their participation.
Trapattoni will certainly enter the Carling Nations Cup ties with Northern Ireland and Scotland relying on a makeshift defence.
However, O'Shea will miss those games anyway, as he is on club duty with Manchester United for the Champions League final against Barcelona on May 28.
