Stockholm - Sweden's Robin Soderling is hoping to return to action at the Rotterdam Open in mid-February after six months out with mononucleosis.
"For the moment we don't have the exact date of his return. He's feeling better but it's important not to rush his return so as not to suffer a relapse," his agent Nina Wennerstroem told the daily Dagens Nyheter on Monday.
The world No 12 is struggling to recover from the illness and has cancelled all engagements up until the February 13-19 Rotterdam tournament.
The former world No 4 has not played since mid-July when he won in Bastad - his fourth title of the season after Brisbane, Rotterdam and Marseille.
The 27-year-old is a two-time French Open runner-up.
