James Tavernier is a doubt for Rangers' Europa League clash with Royal Antwerp after limping out of training yesterday, according to reports. 

The Daily Mail say the Ibrox skipper picked up a knock in training and he now faces a sweat to be fit for the last 32 clash.

It is understood that Scotland international Ryan Jack is on standby to step in for the injured Tavernier at right back if need be. 

The Englishman will face a late fitness test before Thursday's match to determine whether he is fit and able to play his part in the match.
