The 28-year-old came off the bench in Wrexham's 2-0 loss to Blackburn Rovers at Ewood Park last time out having missed three successive matches with a groin issue.

Max Cleworth and George Thomason returned to training earlier this month after sustaining hamstring and thigh injuries respectively earlier on in the campaign.

The duo did not travel with the Red Dragons to Blackburn, although Parkinson suggested both players are close to being available for selection.

"Sheafo has got through the week, he's trained well, he's made another step in the right direction," Parkinson said ahead of his side's Championship contest with Sheffield United at Bramall Lane on Friday night (20:00 GMT).

"Max and Tommo, they weren't with us (at Blackburn) on Saturday but they stayed here and trained. They've also had good weeks on the training pitch as well.

"We've had a good day today, we'll assess those two going into the weekend.

"At the very least, they strengthen up the numbers as we go into these three games in eight days."

Josh Windass, Liberato Cacace and Nathan Broadhead will miss the fixture with the Blades.
