Warnock won’t be able to call upon Hayden Coulson who is ill, or George Saville and Paddy McNair who are away on international duty.
Our Boro writer Joe Nicholson has picked the starting XI he thinks could play – scroll down and flick though our picture gallery to see if you agree:
1. GK: Dejan Stojanovic
Looks like he will start the season as Boro's No.1 goalkeeper yet the shirt is clearly up for grabs. Photo: Getty Images
2. CB: Anfernee Dijksteel
Impressed on the right of a back three at the end of last season and has operated in the same position during pre-season. Photo: Clive Brunskill
3. CB: Grant Hall
Looks set to make his Boro debut and should be a key player for the Teessiders this season. Photo: MFC
4. CB: Nathan Wood
Dael Fry is available again but missed last week's trip to Cornwall and is getting back up to speed. Warnock has been impressed with Wood and may want to take a closer look at the youngster. Photo: Matthew Lewis
