Sunderland's John O'Shea has been training on his own in a bid to return to fitness before the end of the season, according to Dick Advocaat's comments in the Northern Echo.
O'Shea missed out on Sunderland's game against Everton at the weekend with a rib injury and he is still not fit enough to train with the rest of his teammates.
The Republic of Ireland international is determined to make it back to fitness as quickly as possible, though, and he has been going through his own personal training schedule to keep his fitness levels up.
"It’s difficult to say (if he will be available on Saturday),” Advocaat said. “He has trained separately, so we’ll see on Thursday.”
If O'Shea can come back it would be a boost for the team, but Sunderland didn't seem to miss him against Everton.
Advocaat's men were pegged back for much of the contest, but they defended admirably in that tie with Sebastian Coates doing a good job at the heart of their defence.
It means that even if O'Shea is available to face Leicester City at the weekend there is no guarantee that he will win his place back.
Sunderland's game against Leicester is a hugely important one and if Advocaat is able to guide his side to victory then their Premier League status should be confirmed for another year.
