Neil Warnock's Middlesbrough are looking to go into the play-off places with all three points on Saturday.
Middlesbrough come into this one winning four of their last six, winning their last Championship game two weeks ago against Wycombe Wanderers.
Aitor Karanka's Birmingham City will be wanting to distance themselves from the relegation places, currently sitting just four points clear.
After a solid display in their 3-0 defeat to Manchester City last weekend in the FA Cup, they will be looking to build on that performance with a win.
Middlesbrough are low on the injury front, but Ashley Fletcher is still out with a hamstring injury, while Grant Hall is still out with a long-term thigh injury.
Birmingham will be without Alen Halilovic and Gary Gardner because of groin injuries, while Marc Roberts and Kristian Pedersen may return after being out because of knocks.
Bettinelli; Dijksteel, Fry, McNair, Bola, Morsy, Saville, Browne, Tavernier, Johnson, Akpom.
Etheridge; Dacres-Cogley, San Jose, Clarke-Salter, Friend Kieftenbeld, Sunjic, Sanchez, McGree, Leko, Jutkiewicz.
Ones to watch
Neil Warnock said that he couldn't think of a better player he has ever managed than McNair, which is saying something when it comes from such an experienced manager as Warnock.
A move to centre-back this season has proved to be a brilliant move for the Northern Irishman, with him being one of the best this season in the division. Expect him to be a nuisance for the Birmingham attack.
Arriving from Spain in the summer, Sanchez is getting to grips with life in England but is adapting well.
One goal and three assists already this season, his pace and trickery on the right-hand side has proved beneficial for the Blues on the counter-attack, and Warnock is for sure going to want to keep him contained.
These two sides last met four weeks ago at St Andrews, when Middlesbrough picked up a comfortable 1-4 victory, goals coming from Britt Assombalonga, George Saville, and a brace from Lewis Wing.
