Serbian tennis player Janko Tipsarevic has suggested in an Instagram post that he is planning to make a decision on whether to retire or continue his career in the next few months. The 34-year-old hasn't played since last year's US Open.

Back then, the Serb came from two sets down to beat Australian Thanasi Kokkinakis in the first round, before losing to Argentina's Diego Schwartzman in the second round. Tipsarevic called it a season shortly after the US Open to undergo a surgery on both hamstring tendons.

The Serb hoped to return to action in the first quarter of the 2018 season -- but it never happened as he was forced to undergo yet another leg surgery in March. The 34-year-old underlined that the surgery was a must if he wanted to give himself a shot at making a comeback to professional tennis once again.

Tipsarevic spent this past couple of days hanging out with good friend and 14-time Grand Slam champion Novak Djokovic.

Tipsarevic appeared to be set to make his long-awaited comeback this past September at the Banja Luka Challenger.

Unfortunately, Tipsarevic wasn't ready to feature the Banja Luka event -- though he was given a main draw wildcard by the tournament organizers. Tipsarevic is a four-time ATP champion and a former world No. 8 Also read: Todd Martin tips Novak Djokovic to become record Grand Slam champion
