Lyon, France (SportsNetwork.com) - Lyon will be without leading scorer Alexandre Lacazette because of a thigh injury when the club takes on PSG on Sunday in an important top-three clash in Ligue 1.

Lyon will enter the fixture two points clear of the defending champions, but the absence of Lacazette is a huge blow to the league leaders, who are attempting to hold off PSG and Marseille in a close three-team title race.

Lacazette sits atop the scoring chart in Ligue 1 with 22 goals, but he failed to feature against Monaco last weekend after leaving Lyon's 2-0 win over Metz the previous match with the thigh problem.

Lyon sputtered to a 0-0 draw against Monaco without Lacazette in the team last weekend, and the leaders must now find a way to generate some offense without their top threat.

Midfielder Nabil Fekir is second on the team with eight goals in Ligue 1, while Clinton Mua Njie is most likely to take Lacazette's place in the team with the 21-year-old having scored one goal with five assists in 18 appearances.
