The former Middlesbrough captain has been on the outer this season and linked with a move away.
But Brown said: "George has been out of the team and then he's found himself thrown in on the back of two great performances by Jimmy Bullard.
"I said to George that I didn't want him to be Jimmy Bullard, I wanted him to be George Boateng. Last night was vintage Boateng. His experience was like a shining light out there and he deserved the three points as much as anybody."
