Wales wing George North believes he is "symptom free" in his battle with concussion but is uncertain when he will play again.
North sustained his fourth head injury in five months during Northampton's Premiership clash with Wasps in March and has not played again since.
Wales boss Warren Gatland has said he has serious concerns over North's future in the game and wants him to stay on the sidelines until the World Cup.
"It's looking positive," North told The Daily Telegraph.
"I am symptom-free at the moment."
North could play before the end of the season again as Northampton have finished at the top of the Aviva Premiership table which guarantees them a home semi-final.
However, there will be plenty of risk involved if he does return to action with the Saints as another concussion could keep him on the sidelines for six months or more according to medical advice.
The 23-year-old admits that it's a difficult decision to make as he would love to make a return to the playing field soon but he is also aware that it all depends on how his body reacts to the medical examinations he is still undergoing..
"This is my time of the year, isn't it?" North added.
"When you dig in through pre-season and then through the winter months of December and January, you want to get to when the weather is better, the pitches quicker and you want to be able to play some good rugby.
"Obviously, again, I have got to take my time with this and get it right."
