Stan Wawrinka suffered another injury setback as a knee problem forced him to retire from the Open 13 Provence in France.

Three-time grand slam champion Wawrinka’s previous campaign was cut short by a knee injury, and an issue surfaced again in Marseille against qualifier Ilya Ivashka, where he called it a day after two games of the second set.

Wawrinka had a problem in the seventh game of the first set, which he lost 6-4, before deciding he could not continue in the second when it was tied at 1-1.

Elsewhere, Nicolas Mahut and Tomas Berdych each came from a set down to respectively beat sixth seed Gilles Muller and Stefano Travaglia.

Filip Krajinovic beat Gilles Simon in straight sets while Karen Khachanov only dropped three games in progressing past Mischa Zverev.
