Chelsea were leaking too many goals and chances to the opposition for Conte's liking and he made a decision to act.
The Spain worldwide has been on four yellow cards since the 3-0 defeat to Arsenal, and has not picked up any warnings, which will lead to an immediate suspension.
"Diego is showing he can control himself", Conte said ahead of tomorrow's trip to Middlesbrough. I think he's fantastic [at] this.
"When we have the ball you can see that he can have freedom, but always to respect the other roles and the other two strikers, (Diego) Costa and Pedro", Conte added. [Diego] Costa had a bit of an injury after the Everton game, he started to train with us on Wednesday and his physical condition is good.
Costa goes into the Londoners' match against Middlesbrough today sitting atop the Premier League scoring charts with nine goals from 11 matches, while also providing three assists.
The Chelsea boss also added that Eden Hazard has recovered well from a knock he received during worldwide duty with Belgium and will be in the squad at the Riverside Stadium.
The Spain global has scored 9 goals in 11 league games so far and is now the best striker in the country. The same for Eden. It's important to continue, to continue to work, to continue to work very hard, to have this commitment, this work-rate, during the training sessions, during the game. He's an example for all. "I want my players, when they have spare time, to take responsibility above all because, when I was a footballer, I had this type of experience after games. I see the players and I'm very happy to play with this formation".
"It's fantastic to see his work during the games, but also in training".
The 25-year-old puts his current form down to Conte's belief in him and says he is thoroughly enjoying his football and relishing the opportunity given to him in the present set up at the club.

With Costa fit and midfielder Cesc Fabregas and defender Kurt Zouma fit again, Chelsea have no injury concerns. "You must play with high intensity to win".
The 5-0 defeat of Everton came prior to the worldwide break, but Conte hopes his players can resume where they left off.
