Southampton forward Dusan Tadic could play in a facemask during his side's Europa League group game against Hapoel Be'er Sheva on Thursday.
Tadic, 28, has not featured since breaking his nose while playing for Serbia against Wales in November.
Saints will finish second in their group and reach the last 32 with a win or a goalless draw.
But a win for Hapoel, or a score draw, would see the Israeli side progress to the knockout stage.
Teams that finish level on points in their group are separated by the results in their head-to-head meetings, followed by away goals scored in those games and then finally overall goal difference.
