NEIL WARNOCK remains cautious about throwing untried youngster Josh Coburn into senior action, despite Middlesbrough effectively having nothing to play for in the final four games of the season.

Coburn is expected to be named on the bench when Boro travel to Rotherham United tomorrow night, but having been an unused substitute in last weekend’s home defeat to QPR, it remains to be seen whether the 18-year-old forward is handed a senior debut at the New York Stadium.

“What I don’t want to do is kill them (young players),” said Warnock. “Young Josh has done so well, but he’s had good games in the Under-23s and bad games in the Under-18s. He’s a little bit hot and cold, so it’s a question of whether to chuck him in at the deep end. I still think he’s going to get time, but it’s as and when really.”

Jordan Archer will continue in goal tomorrow, but Nathaniel Mendez-Laing is unavailable because of injury.

Rotherham are without loanee Lewis Wing, who is unable to play against his parent club.

Middlesbrough (probable, 4-2-3-1): Bettinelli; Fisher, Hall, McNair, Bola; Howson, Saville; Watmore, Kebano, Bolasie; Akpom.
