Brighton manager Graham Potter has talked up the endurance of defender Ben White.
The 23-year-old has played more games than any other Brighton player this season with 34.
But the Seagulls will have to do without him when they face Sheffield United after White was sent off against Chelsea earlier this week.
"He was an ever-present player for Leeds and has been for us. He has got that athleticism where he can just play, play, play.
"We have to find a solution, we have got options and we will have to think about that over the next day or two, but we will miss him."
