Robson has been struck down with illness and has had to withdraw meaning that there will only be six substitutes on the Boro bench at the Ricoh Arena as Middlesbrough look to win only their second away game of the season.
Julio Arca takes his place, while there is also a recall for Gary O'Neil and that means Mikael Tavares has to revert to his role on the sidelines against a Coventry team fielding former Middlesbrough loan man Marlon King.
