Newcastle United boss Eddie Howe admits they've suffered a double injury blow in their Champions League defeat to Borussia Dortmund.
Both Alexander Isak and Jacob Murphy were forced off during the 1-0 loss.
Howe later said, "That [Isak going off] was a blow and Jacob came off with what looks like a serious injury.
"We've got a small squad as is it. That's probably the most disappointing thing of the night.
"It looks like a recurrence of his [Isak's] groin problem and it's a big blow. Jacob looks serious, potentially a dislocation of his shoulder."
