MILLWALL striker Josh Coburn could be out for up to eight weeks – leaving Lions boss Neil Harris with just one senior striker.
Coburn, 21, enjoyed a dream Millwall debut when he scored in the 3-0 win against Sheffield Wednesday before the international break.
But Coburn only last 34 minutes of his second game, the 1-0 defeat to Luton Town at The Den on Saturday, as he injured his calf.
Macaulay Langstaff replaced Coburn and had a great chance to equalise but was denied by Hatters goalkeeper Thomas Kaminski late on.
Harris is also without the injured Tom Bradshaw and record signing Mihailo Ivanovic.
It leaves Langstaff as the only recognised senior centre-forward.
