PARIS, Feb 5 (Reuters) - Paris St Germain defender Mario Yepes will be out until the end of the season with an ankle injury, the Ligue 1 club said on Monday.
The Colombian centre back was injured during Sunday's 1-1 draw at arch rivals Olympique Marseille.
'It is a huge setback for the club,' PSG chairman Alain Cayzac told reporters.
Yepes will have more tests on Tuesday to assess whether he needs surgery.
PSG are 17th in the 20-team Ligue 1, a point above the relegation zone.
