Jose Maria Olazabal will return to golf after 18 months out at the British Masters.
The two-time major winner and triumphant 2012 European Ryder Cup captain has been out of action since the 2015 Masters due to rheumatoid arthritis.
However, the 50-year-old will be back in action in Hertfordshire this week, with a trip to the Portugal Masters pencilled in for the following week.
The Spaniard stated the two tournaments will play a big role in how he decides to carry on with his career.
"I want to see how the body can cope with the regular competition, rhythm of practice and 18 holes. Lately, I've played 18 holes two days, nine holes another two days - I've been alternating that way," Olazabal told the European Tour's official website.
"The two weeks at the British Masters and Portugal Masters will be a good test to see if I can stand up all day.
"I want to see how it goes during the two weeks, and that will help me to take a decision on whether I will keep on playing the European Tour or the senior circuit next season. We'll see how it goes.
"Although I'm feeling better, I'm still not at a 100 per cent. The pain is not so bad now, it gets a bit painful from time to time but I think that's just getting old."
