Burnley have lots of injuries, Ramsey , Sarmiento, Beyor , Benson and Tresor. That was Fosters first game back for a while. All very good players too all would be in and around their first team.
People forget they went up and broke the bank, there team can handle 5/6 injuries and still leave Koleosho (who was linked to Bayern Munich at the start of the season) as an unused substitute.
Burnley even with those injuries didn’t have one youth team player on the bench.
Leeds have a big squad they have 4 injuries to what you would call first team players. They don’t have a single youth team player on the bench.
