Charlton Athletic vs Middlesbrough - Charlton's Yaya Sanogo to miss Middlesbrough clash

Relegation strugglers Charlton will be without Yaya Sanogo when they host high-flying Middlesbrough on Sunday.

Striker Sanogo, on loan from Arsenal, starts a three-match ban after he was dismissed for an off-the-ball elbow on Antony Kay in Tuesday's 0-0 draw with MK Dons.

Goalkeeper Stephen Henderson will be assessed after missing two games due to a dead leg, with Nick Pope on standby to deputise again.

Alou Diarra, Chris Solly, Igor Vetokele, Patrick Bauer, Johnnie Jackson, and Ahmed Kashi remain injury doubts but Harry Lennon has completed a three-match ban.

Middlesbrough have announced that head coach Aitor Karanka will not be in charge for the game having not taken training on Saturday. Steve Agnew will be in the dugout for Boro.

Skipper Grant Leadbitter is back for the trip to south-east London after he made a full recovery from his recent hamstring strain.

Leadbitter sat out the shock midweek defeat to Rotherham on the bench but is expected to return.

Defender Daniel Ayala is set to miss out again as he undergoes more tests on his problematic hamstring strain.
