Rangers have confirmed on their official website that midfielder John Eustace has been handed a trial period for the next three to four weeks.
Eustace, 35, is a free agent having been released by Derby County earlier this summer, and will therefore be on the lookout for a new club.
With his former Watford coach Mark Warburton now the manager at Rangers, it seems that a move to Ibrox could be on the cards this summer.
Rangers have confirmed that talks have been held between Eustace and the club, but with concerns over a knee injury sustained in January, Eustace will now begin a trial period with Rangers next week.
The veteran midfielder will now have the chance to prove his fitness to Warburton, who admires Eustace's leadership qualities and professionalism, according to the Rangers official website.
Rangers have so far signed three players; goalkeeper Wes Foderingham and defenders Danny Wilson and Rob Kiernan, with all three in their early 20's.
Eustace is an entirely different case. At 35, Eustace doesn't have many years left at the top of his game, and the knee injury sustained in January means he hasn't kicked a ball for almost six months now.
Warburton and Rangers are doing their due diligence here, making sure that Eustace can cope with the training sessions at Ibrox ahead of a potential move.
