Leon Balogun, a Nigerian defender, has emerged as a huge health worry for Rangers ahead of Saturday's trip to Celtic Park.

The 35-year-old was substituted at halftime in Rangers' 4-1 home triumph against Kilmarnock last weekend.

The centre-back has recently returned to the Rangers' starting lineup after Connor Goldson was sidelined for the remainder of the season.
According to manager Phillipe Clement, Balogun is not totally fit for the crucial championship race showdown.

"Leon Balogun is uncertain; no other new injuries or players returning from injury.

Rangers are three points behind Celtic in the Scottish Premiership table.
