The Leinster winger went down clutching his left leg and faces a wait to determine the severity of his injury
Luke Fitzgerald is a doubt to face Wales next weekend having suffered a left knee injury at Ireland training yesterday at the Aviva, according the reports in the Irish Independent.
Fitzgerald was withdrawn from training after the incident and did not return, leaving his involvement in next Sunday's clash against Warren Gatland's Wales side a doubt. He was expected to be named in Joe Schmidt's 23 man squad at a bare minimum and with Schmidt preferring to hold off on naming a team, Fitzgerald might have had time to impress his coach further during the week.
Ireland will release a medical update on Tuesday and it will be a long wait until then before Irish fans are updated on the severity of the Leinster wingers' knee injury.
Fitzgerald understands how frustrating it can be to be sidelined having fought back from serious hip and groin injuries to earn an Ireland recall last year and said of his injuries at the time, "I did (fear for my future) actually. I felt there was no escaping it really. The guys were unbelievably patient with me. There were a couple of times when I just walked out and said 'I can't, I can't do this. I've done months of rehab and I still feel like I'm going nowhere."
Fitzgerald has 34 caps for Ireland and at 28 years old will want to add to that in the upcoming Six Nations provided his knee injury isn't too serious.
