Paris:Lionel Messi will miss Paris Saint-Germain's next French league game at last-placed Metz after a knock to his left knee.
A scan confirmed "the signs of bone contusion," PSG said in a statement on Tuesday. Another assessment of Messi will be made in 48 hours.
Messi was taken off in the 75th minute of his home debut on Sunday, when PSG beat Lyon 2-1 in the league.
