Southampton boss Ronald Koeman’s place at Sunday’s Premier League opener is in jeopardy.
The Saints boss ruptured his Achilles in training on Wednesday, and is on crutches with his foot in a protective boot.
Assistant Erwin Koeman suggested his brother may not be able to travel to Newcastle.
“He knows he has already some problems with his Achilles, and if you are involved in a training sessions then s*** can happen like what happened,” he said.
“OK, we will hear tomorrow what happened and we will hear tomorrow if he is on Sunday on the bench or not.”
