Robbie Keane has joined up with the Republic of Ireland squad to play Brazil at the Emirates Stadium on Tuesday following a reassessment of a knee injury.
The Celtic striker had been a doubt for his club's Old Firm clash against Rangers on Sunday but started the game, almost scoring with a volley in the first half.
Despite playing the full 90 minutes the 29-year-old was then ruled out of the Brazil match due to a recurrence of the problem.
However, he was examined on Monday and was freed by Celtic to travel to London to link up with the Irish squad for their first match since the controversial World Cup play-off defeat to France in November.
