Norwich City head coach David Wagner confirmed that Onel Hernández's scan came back clear, while there will be a late call on Josh Sargent.
"Onel had a scan yesterday, and it's clear. It looks like he's ready. Whereas, Josh didn't train today. He will be a late call for Saturday," he said.
"Onel felt his hamstring in the first half, and we had the discussion at half-time. He wanted to try it in the second half. Josh was the same, he was limping in the first half. It was clear we had to take them off early in the second half.
"It looks like (Shane) Duffy will be out for two weeks. (Jonny) Rowe doesn't need surgery, and it will be more months than weeks as it's a serious injury. It's hard to give a clear time frame on this.
"He \[Rowe\] is a big player for us, and is still super young. He can deal with situations like this, and has done fantastic in the past. I'm confident that he'll come back through this."
Wagner also spoke about Saturday's opponents, Cardiff, highlighting the threats the Bluebirds will pose.
Norwich claimed the three points when the two sides met at the Cardiff City Stadium in November.
"I think we're on a completely different run to back then \[the 3-2 win in November\]. It's obvious, from the points and the performances. Hopefully we can push the squad for Saturday. It's been a heavy week, but we're confident.
"We know they're not on the best run at the moment, but I think they're unlucky. It's a super competitive team, nobody thinks this will be easy. They have very good individuals."
