The 34-year-old, who scored a 45th try for his country in last weekend's win over Wales, is expected to feature against England in Dublin on Sunday.
Despite persistent rumours over his future, O'Driscoll insists that he is taking one game at a time.
"Winning man of the match against Wales doesn't have a bearing. It's a nice reminder that it's still there," he said. "But with regards to the decision-making process, because I'm not thinking about it, it hasn't altered my thinking.
"I'm at game two, feeling okay and looking forward to England."
O'Driscoll has made 121 appearances for Ireland since his debut in 1999.
