Nigeria defender, Leon Balogun, is a major doubt for Rangers’ old firm derby against Celtic.

DAILY POST reports that the encounter is slated for the Celtic Park on Saturday.

Balogun sustained a muscle injury in Rangers’ 4-1 win against Kilmarnock last week.

The 35-year-old was replaced at half-time by Ben Davies.

The centre-back could sit out the title decider unless he recovers on time before the game.

Rangers are three points behind leaders Celtic on the table and must win the game to have any chance of winning the Scottish Premiership title.

Brendan Rodgers’ Celtic won the first meeting last September 1-0 with Kyogo Furuhashi scoring the decisive goal.
