Hull City strikers Abel Hernandez and Will Keane will be "out for some time" after picking up injuries in the Tigers' 2-1 victory over Southampton.
The duo were forced off inside the first 25 minutes at the KCOM Stadium on Sunday and head coach Mike Phelan said "the signs aren't very good".
Keane limped off with a knee injury while Hernandez has a groin problem - both will be assessed on Monday.
"Keane is the worst of the two, it's a case of wait and see," said Phelan.
"They are crazy injuries. There is no reason why, it's just the wrong place at the wrong time.
