Andy Murray has entered the European Open in October as his comeback schedule continues to take shape.
The Scot has already committed to two tournaments in China at the end of September – the Zhuhai Championships and the China Open – and will also play in Antwerp beginning on October 14.
Murray's successor as British number one, Kyle Edmund, is the defending champion having won his maiden ATP Tour title last year.
Murray played his first singles match since January's Australian Open in Cincinnati last week, losing to Richard Gasquet, and was also beaten in the first round of the Winston-Salem Open on Monday by Tennys Sandgren.
The former world number one is now likely to drop down to second-tier Challenger level as he looks to return to fitness following hip surgery and head to Majorca for next week's event at Rafael Nadal's academy.
His probable option the following week, if he wanted to play again, would be a tournament in Cassis, France.
Murray's brother Jamie has helped organise the Murray Trophy, a Challenger tournament in Glasgow, next month but, given it is the week before Zhuhai, Andy would probably be unable to play.
