JONNY Smith is a major doubt for Swindon Town's home game with Burton Albion tomorrow (3pm).

The on-loan Bristol City attacker came off with breathing problems 30 minutes into Town’s 2-0 defeat at Blackpool last weekend.

Boss Richie Wellens says the 23-year-old – who is asthmatic – is unlikely to be available for selection after returning to his parent club this week.

"He’s not trained with us all week," Wellens told BBC Radio Wiltshire. "He’s had steroids Monday and Tuesday, he went to Bristol City Wednesday and we’ll wait and see what they come back with.

“I would imagine he’d be pretty doubtful at this moment in time, simply because he hasn’t trained all week and with something where it’s his asthma we need to be careful.”

When asked what caused Smith’s problems, Wellens added: “He woke up on Saturday morning, I think something had been up with the air conditioning in his hotel and he wasn’t happy with it, then you could see the look on his face, he wasn’t happy.

“It was best to bring him off and make sure he’s on the right medication and try and get him fit as soon as possible.”

Wellens also has concerns over new loan signing Jordan Stevens, who has a blister.

“You sign a lad from Leeds who you think is going to be toughened up by Leeds but he’s pulled out of training today with a blister," Wellens said on Wednesday.

“To be fair to him, it’s a big blister so we’ll let him off.

"He’s trained in the 11v11 game and he’s very quick, quite bright, very clever in the final third so he’ll give us another option.

“He’s very similar to Jonny Smith, in the way that he moves, he glides across the ground.

“We just need to make sure that his blister’s right and come Friday, if it’s healed sufficiently, he can train and be ready for the game.”
