Swindon boss Scott Lindsey believes Harry McKirdy will be on his best behaviour at Brunton Park today.
The former Carlisle United player returns to take on his former club.
McKirdy's latest reunion comes six months after he inspired Swindon to a 3-0 win in Cumbria - and taunted Blues fans with his celebrations.
Lindsey, though, said he hopes the 25-year-old will concentrate on his football this afternoon as he returns from suspension.
McKirdy saw red against Salford City last weekend thanks to bookings for dissent and a challenge.
“I’m hoping this isn’t the worst game for him to come back for, I’m hoping it actually has the opposite effect and he concentrates on the job he needs to do more," Robins head coach Lindsey told the Swindon Advertiser.
“I’ve said it before about Harry - he’s only happy if his football is going well, so I think he’s determined to behave himself this weekend.
“I’ll speak to individual players about certain things, and that’s something I’ll probably bring up with him.
“But there will be other little bits of information that will be drip-fed into the players along the way, so I will probably mention [discipline].”
Swindon, losing play-off semi-finalists last season, have one point from their first two games this campaign, and are yet to score in league and cup.
Injury-hit United, meanwhile, will be out to make it seven points from nine.
Lindsey says he is under no illusions about the test facing his team in Cumbria.
He said of Carlisle: “They’re a very challenging prospect. They’ve had a good start to the season.
“In their first game, they beat Crawley 1-0. I watched the game, they were very competitive.
“They put a lot of balls into your box, and they cross from different areas, so we’ll have to be ready for that.
“And they went to Colchester last weekend and got a good point at a hard place to go.
“They’ve had a good start to the season, and they’ve got a really experienced manager in Paul Simpson, so we know it’s going to be a very, very tough game.”
