Leo Hjelde

Hjelde (appendectomy) featured in Wednesday's Papa John's Trophy loss to Crewe Alexandra.

Hjelde will miss some time after undergoing an appendectomy, William Jackson of LeedsLive reports.

Hjelde (knee) is on the bench for Saturday's match against Watford.

Hjelde underwent knee surgery, but he's already walking without a limp and could be back within weeks rather than months, according to manager Jesse Marsch.

Hjelde will miss at least three weeks after suffering a knee injury in last weekend's loss against Everton, according to manager Marcelo Bielsa. "Hjelde has an injury in his knee and if the process in the next three weeks is effective, he would be available in that time. But it could happen that he may not recover in those 20 days, which would result in him having had to surgery."
