Listen to Phil Parkinson speaking about the striker's knock here.
Billy Clarke is to have tests on a knee injury after limping out of Bradford's clash with Shrewsbury on Saturday.
The striker scored in the first half but was forced off after the break.
The game finished 1-1, with the Bantams picking up their first point of the season.
It's not yet known for how long Clarke could be out.
Manager Phil Parkinson told Pulse 1 Sport after the game: "He's damaged his medial ligament.
"To what extent we don't know yet.
"It's a real blow for him and for us because he is a real talented player.
"He was picking the ball up in some dangerous positions [against Shrewsbury] and drawing fouls and in the end they have got him off the pitch by injuring him- which is a shame."
Pulse 1 Sport is back on Tuesday evening with build-up to exclusive full match commentary of Bradford City vs Gillingham. Jason and Stix will be on air from 7pm.
