Kim Hellberg says Middlesbrough's new arrivals Leo Castledine and Fin Munroe could feature at West Brom on Friday night (20:00 GMT).
Attacking midfielder Castledine arrived from Chelsea on 9 January after a stellar loan spell with League One Huddersfield while left-back Munroe, also 20, joined from Aston Villa on Thursday after impressing on loan at League Two Swindon.
Hellberg told BBC Radio Tees: "They are two young players that want to develop that suits the environment we have, I am happy with them.
"They are, I think, ready to play in the first team, we'll see if it comes to that [on Friday].
