Rangers assistant boss David Weir has told the Daily Record that John Eustace's knee injury has been fully checked out, and now it's down to the player to get fully fit.
Eustace, 35, is a free agent having seen his Derby County contract expire earlier this summer, and is in line to reunite with his former Watford coach Mark Warburton having joined Rangers on trial last week.
The veteran midfielder is now looking to impress Rangers in order to win a contract, but concerns over his fitness have been magnified in recent weeks.
Eustace suffered a season-ending knee injury in January, and having not played since then, there are very valid concerns that the player could struggle to recover and return to his best form.
However, Rangers assistant boss Weir has told the Daily Record that Eustace's knee has been checked out - but the player must now get fit in order to earn an extended stay at Ibrox.
"Everything's all right with John's knee," said Weir. "There's no doubt he's been checked out, it's just a matter of getting fit now."
Long trial needed
Eustace has a wealth of experience from his time in English football, but the concerns over his knee injury need to be fully investigated by Rangers.
Whilst most trials last from a few days to a week, Eustace needs to be with Rangers for three, maybe even four weeks in order to fully assess how he can cope with his knee.
Rangers can't afford to rush into a decision with Eustace, and given his age, the injury will be on the mind of manager Warburton - even if Weir says that the injury has been checked out.
