Ireland centre Brian O'Driscoll will make a decision on whether to retire in July following the conclusion of the Lions tour.
O'Driscoll, who returns following a three-week suspension for stamping this weekend, is tipped to be selected by Warren Gatland for the Lions tour of Australia, but his future beyond the end of this season remains unknown.
"Who knows what the final act will be in my career. I just have to play it out this season and see how things unfold. Then I'll make a call after that," said O'Driscoll to the Lions website.
"I'm not under any massive pressure to make a decision. I will see what happens over the next few months and take a look at things in July."
Australia would mark O'Driscoll's fourth Lions tour, 12 years on from his memorable try in the first Test against the Wallabies in 2001.
"Playing for the Lions is the ultimate in your career, such a massive honour. You only have to look at the quality of some of the players who have never been on a Lions tour to realise that," added O'Driscoll.
"Playing in that calibre of team, and training day in, day out with that level of player, brings out the best in you. It's hugely exciting.
"I would love to be a part of a Lions team capable of winning a Test series and I think the team being put together by Warren Gatland is definitely capable of doing that in Australia. It's not a question of me having some unfinished business after 2001 - I just want to play in a winning Lions team.
"You can't really allow yourself to think too much about Lions selection in April. It is a serious time of the season for a lot of players and certain players will be hopeful of getting selected. But you just have to keep on trying to improve and make a few more headaches for the coaches.
"It is the last chance to leave a lasting impression and I will be no different to any other player in that respect this month. You mustn't over think it - just get on with what you do week in, week out."
