Chelsea boss Jose Mourinho refused to blame John Terry after his dismissal at West Brom - but believes appealing the red could be a waste of time.
The defender was sent off early in the second half for pulling back Salomon Rondon to continue his difficult start to the season.
Chelsea hung on for a 3-2 win at The Hawthorns to record their first Premier League victory of the season after Pedro's debut goal set them on course for the win.
Terry retained his place after being substituted during last week's 3-0 defeat at Manchester City and Mourinho feels appealing the sending off would not be worth it.
Normally it's a waste of time for us, I think we should but normally it's a waste of time. (Nemanja) Matic against Burnley last year was a waste of time, Diego Costa against Liverpool was a waste of time.
No (I don't blame him), it's a ball into the space behind the full-back, the fullback is pressing high, the striker makes the movement and then (referee) Mr Clattenburg decides it's a red card.
To speak about the sending off I have to speak about many other things in the game. Some things you can see and some things we can see.
I prefer just to focus on us. Tomorrow the back pages have to be different because we won.

New signing Pedro scored one and set up another goal for Diego Costa in an entertaining first half as Chelsea went into the break 3-1 ahead at West Brom.
The Spanish international slotted the visitors in front after Thibaut Courtois, returning from suspension, has denied James Morrison from the spot.
The Scot missed his spot kick with scoreline still goalless, but he made amends by pulling one back for Tony Pulis' side.
That seemed to give West Brom hope of salvaging something from the game, but Casar Azpilicueta popped up with a goal late in the first-half to give the home side a mountain to climb.

Chelsea boss Jose Mourinho says a 60-second conversation was all that was required to convince Pedro to sign for the Premier League champions.
Mourinho became aware of the availability of the Spain forward on Monday and Chelsea signed him for £21m on Thursday, swooping swiftly for a player Manchester United had pursued for around a month.
The World Cup winner joined Baba Rahman, a left-back signed from Augsburg, in moving to Chelsea in the wake of the 3-0 loss at Manchester City.
Both could make their debuts in Sunday's match at West Brom as Chelsea bid to recover from their worst start to a season in 17 years.
"For me, it was one minute," said Mourinho, before recalling the conversation.
"'Is it true that you want to leave Barcelona?' 'Yes, it's true. I love it here. It's my home, but it's time for me to move.' 'Did you sign already for another club?' 'Almost, but not yet.' 'Do you want to come here?' 'Yes, I want.'
"I told people in the club 'it's over to you'. (But) I thought he would never leave Barcelona."
