Saint-Etienne forward Romain Hamouma will be out for a month with a hamstring injury sustained against Metz on Sunday.
Hamouma's free-kick off both posts resulted in John Boye scoring the own goal that won ASSE the game last weekend but the 33-year-old Hamouma later went off with what looked a serious injury.
Tests ruled out an ACL rupture but did reveal a lesion to the hamstring that will sideline Les Verts' four-goal leading scorer for between four and five weeks. Hamouma, at the club since 2012, is out of contract at the end of the season.
