The all-action attacker also hurt his knee in the 1-1 draw, but played through the pain.

At this afternoon’s press conference, McKenna confirmed Szmodics had also suffered an arm injury.
“Yeah, he’s recovering well,” he said. “There was a bit of fear that it might have been a break, but x-rays have cleared that up.
“He’s got some really heavy bruising there, but he’s recovering well.”
Of the rest of the squad ahead of Saturday’s trip to Preston, he added: “We’ve had one or two little issues from the game that we’re still getting assessed.
“The squad’s probably not quite where we would like it to be in terms of numbers for this stage of the season, but we’ll have plenty to be competitive on the pitch on Saturday – and hopefully enough on the bench to make a big impact as well.”

New loan signing Chuba Akpom hasn’t made a squad since arriving from Ajax, but McKenna confirmed he’ll hopefully play a part at Preston.
“He’s trained with the group now for the last couple of days, so that’s the first time he’s trained full throttle with the group – that’s a step forward,” the Town boss said.
“All being well he’ll be with us for Preston.”

McKenna was also asked about fellow loan signing Jens Cajuste, whom he previously said had no pre-season and thus required careful handling.
The silky smooth midfielder did come off the bench for 20 minutes against Southampton, however.
“He’s closer and we’re hopeful that he’ll build up minutes again this weekend,” McKenna revealed.
“He got maybe 20 minutes on Sunday and we’ll hope to build that up again this weekend, whether that’s minutes from the bench or from the start.
“Again, we’ll have to make the right judgement because there’s a delicate balance to that.
“But it’s really useful to have one (midfielder) here because that’s a department that’s undergone a lot of change, we’ve lost four of the five players from that unit last year.
“We’re really happy to have him.”
