Striker Zlatan Muslimovic and midfielder Luigi Bruins will have trials with Rangers this week, the Scottish Premier League club confirmed on Monday.
Manager Ally McCoist will assess the pair as he bids to get the defending champions title challenge back on track, as they trail Celtic by four points at the top of the table.
Muslimovic, a Bosnia team-mate of Rangers defender Sasa Papac, has been without a club since his contract with Greek side PAOK ended in the summer.
The 30-year-old has scored 12 goals in 33 appearances for Bosnia.
Dutch under-21 international Bruins, 24, is also without a club after leaving Austrian side Red Bull Salzburg last month.
