But boss Gareth Southgate praised the way that the 32-year-old Dutchman reacted to being benched and stressed that he remains an integral part of his plans as Boro battle near the bottom of the table.
"I have to give George credit, he accepted the decision with excellent grace," said Southgate. "His response was very good and he was very helpful throughout the day on Saturday.
"He showed great maturity in taking the decision on board and he remains a very big part of this club.
"Catts has been playing very well and training hard and deserved his opportunity."
