Brian Laws transfer-listed and fined the 28-year-old for head-butting an opponent at Port Vale in August but the Owls boss has revealed the striker may be in the squad to face the Sky Blues after impressing with his attitude and work in training.
"Jeffers might come back into the equation," he told the Sheffield Star. "He's been out in the cold. But his attitude has been first class.
"We might be looking at him coming back into the squad.
"He's been thoroughly professional, not moaned about anything and has worked as hard as anybody else."
