Neil Warnock says he has a decision to make in the right-back role, while two more of his players are set for a return to training.
Darnell Fisher won’t be rushed after an Achilles injury, while Djed Spence also went off with an injury in Saturday’s win over Stoke.
“Darnell’s got a nasty Achilles problem, so I didn’t want to rush him back - especially with [Anfernee] Dijksteel out,” Warnock said.
“Against his old club I’m sure he’ll be busting a gut to be involved.
“I’ll see how they are because Djed [Spence] picked up a knock as well.
“I think both [Ashley] Fletcher and [Marcus] Tavernier are going to be training with us today.
“They could be back before the international break.”
After his first assist at Swansea, Warnock was delighted to see Nathaniel Mendez-Laing bag his first Boro goal at the weekend.
“He’s had to be patient because he came in with other wide players like Yannick Bolasie and Neeskens Kebano, and Marvin Johnson has not put a foot wrong really,” he said.
“I just said to him you’ve got nothing to prove, I know what you can do so just get fit.
“That’s all I’ve asked of him, and I must admit he too his chance with aplomb didn’t he.
“It was a wonderful finish - I loved it.”
Meanwhile, the Boro boss has been pleased with Grant Hall’s return to the side.
“JT [John Thrower] our fitness guy has told us how hard Grant worked,” he said.
“I think he’s feeling the benefits of that now. He looks the leanest he has since he’s been here.
“Him and Dael [Fry] are getting a great understanding.”
