Central defender Chris Riggott goes straight into the Middlesbrough squad for Saturday's Premier League clash with Portsmouth after being recalled from his loan spell at Stoke.
Riggott returned to Teesside with manager Gareth Southgate facing up to the prospect of having to do without Robert Huth (foot) once again and concerns over a series of knocks.
Goalkeeper Mark Schwarzer could return after missing last weekend's 3-2 defeat at Sunderland with a back injury. Both he and Ross Turnbull, who was on the bench at the Stadium of Light despite nursing a similar problem, are back in training, with Brad Jones likely to make way.
Striker Jeremie Aliadiere should be available after shaking off the dead leg which sidelined him for the trip to Wearside, but Gary O'Neil (knee) and Mido (hernia) are out for the remainder of the season after undergoing surgery.
Milan Baros returns to the Portsmouth attack to partner Jermain Defoe after recovering from a calf injury.
The Czech Republic international has not scored in 13 outings for the south coast side but will start in place of the rested Kanu, and David Nugent who will be on the bench.
Goalkeeper David James remains a serious doubt for the FA Cup final with a calf strain allowing Jamie Ashdown to continue in goal while Hermann Hreidarsson returns following his one-match ban and could replace Lauren at full-back.
Squads:
Middlesbrough: Schwarzer, Turnbull, Jones, Young, Taylor, Grounds, McMahon, Wheater, Pogatetz, Riggott, Boateng, Arca, Downing, Shawky, Rochemback, Cattermole, Johnson, Aliadiere, Alves, Tuncay.
Portsmouth: James, Johnson, Campbell, Distin, Lauren, Hreidarsson, Diarra, Diop, Muntari, Kranjcar, Utaka, Baros, Defoe, Kanu, Davis, Nugent, Hughes, Pedro Mendes, Aubey, Begovic.
