Rangers are hopeful John Lundstram will be fit to face Braga after the midfielder trained on Wednesday.
Lundstram was subbed with an injury during Sunday's 4-0 Premiership win over St Mirren but is pushing to return for Thursday night's Europa League quarter-final second-leg.
Manager Giovanni van Bronckhorst revealed yesterday that Lundstram would join his team-mates on the training pitch and that could determine whether he features at Ibrox.
Ryan Jack and Calvin Bassey are both available after being rested for the weekend trip to Paisley.
But Filip Helander 's season is over with Rangers waiting to discover whether the centre-back will require surgery on a foot injury.
Long-term absentees Ianis Hagi and Alfredo Morelos remain out until next season.
