Cowley confirmed Grabara had now been discharged and would undergo further medical examinations to determine when he can think about a return to action.

"Kamil has been discharged from hospital, which is good news. He's much better in himself," Cowley said at a press conference, reported by the club.

"We anticipate, best-case scenario, 28 days. He will see a neurosurgeon, which will give us the length of his injury."

Quoted by local media, Cowley added: "He took a heavy collision to his head and has a small bleed.

"Because there was a disruption of the tissue we have to let that settle. It's not until his bleed has cleared that the seven-day concussion protocol starts.

"First and foremost he is a young boy and an important player to us and we wish him well. Football is important but nothing is more important than your health."

Huddersfield are at promotion-chasing Fulham on Saturday, when Joel Coleman could deputise between the posts.

Ryan Schofield has joined Scottish side Livingston on loan for the rest of the season, and Cowley confirmed Huddersfield were working on arranging some additional cover.

"We are looking at getting another keeper in," Cowley said. "We worked hard yesterday and today to make that happen."
