Tony McMahon doesn't require surgery on his troublesome Achilles problem, but has conceded he will be sidelined for much of pre-season.
The right-back, who missed the Blades play-off campaign with the niggling complaint, recently visited a specialist to decide the next course of action but was told the problem didn't need further treatment.
Commenting on the injury that has plagued him for much of 2013, McMahon said:
"I went to London to see the specialist again last Wednesday and the good news is I don't need further injections or to wear a protective boot.
"The plan now and throughout the summer is to do plenty of strengthening work, but it isn't going to be a quick fix, it will still be the back end of pre-season when I am fully fit.
"I played with the initial problem for two or three months, because of my character I just keep going until I can't go any further and that was the case at Portsmouth.
"It didn't settle down in time for the play-offs which was a massive disappointment personally, but now I have to get things sorted in the summer months.
"I was at both play-off fixtures and it was a real bitter pill to swallow, we should have been capable of reaching the final at the very least but that is history now and we must react positively."
