Wright went for an X-ray following concerns over his shin bone after his side's 1-0 League Cup win over Morton on Wednesday night.
But he looks set to return to action after he serves the final two matches of his three-match Scottish Premiership ban.
Manager Tommy Wright said: "He was feeling a lot of discomfort so we sent him for an X-ray last night but it's all clear.
"He wouldn't have been fit for Saturday but he is suspended anyway.
"And with the international week coming, when he is free from suspension he should be clear from the injury as well."
Saints could have striker Steven MacLean in their squad to face Hearts at Tynecastle on Saturday just two weeks after he was feared to have damaged a cruciate ligament.
Manager Wright said: "He trained a light session today with the under-20s and will train fully tomorrow. If he comes through that he will hopefully be available for selection.
"On the Saturday after the game at St Mirren we did have real concerns about his cruciate, fortunately there was no damage, he had just shaken up his knee.
"But, Steven being Steven, he has trained really hard and returned earlier than we thought."
