Speaking to the Official Club Website, Town physio Dave Williams said : "Kelvin dislocated his middle finger in the last minute of the game, making a save.
"It was literally his last touch of the match. We reset the finger into place straight away but he has to be considered a doubt for Saturday.
"He is not ruled out by any means though and will have a fitness test as late as the boss wants to go."
If Davis doesn't make it, Royle will have a choice of either throwing in youngster Lewis Price for his first senior match, or recall forner Norwich keeper Andy Marshall, who has so far been kept in exile behind both Davis and Price.
