Keane's Republic of Ireland meet Scotland in a crucial fixture in Dublin and the country's all-time leading scorer is determined to play a part.
"Felt it toward the end, obviously. But, thankfully, I got through," said Keane after the match on the weekend.
"It's a massive game," he added. "The atmosphere's going to be great.
"Scotland's the same [kind of intense rival as is England]. It's a massive game for us, and a game we need to get something out of."
