Neil Warnock gave an update on the injuries in his squad, while he also issued a challenge to those fit to be involved in the season run-in.
The manager has outlined what he wants to see from his squad over the next six games, starting with Barnsley tomorrow (3pm).
“I’m interested to see how we handle it, because I don’t think anyone else plays the way Barnsley do,” he said.
“Next season we’ve got to be up and ready for all tests and all types of football.
“The players have got six games to make their case to me - I think one or two players have got to show me desire.
“I’m not a stats man, but I need to see a lot more effort and work-rate if they want to be involved next season.”
The Boro boss will continue to be without several first team faces against Oakwell tomorrow.
“I think Dael [Fry] will come back before Tav [Marcus Tavernier], but they will both be a couple of weeks,” he said.
“We might get them back for the last two games of the season.
“We haven’t got to too much of a timescale on Sam Morsy, maybe six to eight weeks.
“The pandemic has thrown things off a bit, and we’re picking up a lot of injuries - you just have to get on with it.
“The good news is that Anfernee Dijksteel looked good yesterday - I’ve got everybody in the club watching his weight! He’s got to come out firing on all cylinders next season.
“I think they all will be back for pre-season, touch wood.”
