Allen Park — Lions running back Joique Bell practiced fully on Thursday, a good sign after being limited Wednesday with an Achilles injury.

Before the Christmas afternoon practice, coach Jim Caldwell declined to provide clarity on when Bell suffered the injury. He was also non-committal when asked if Bell would play Sunday against the Green Bay Packers.

"We'll see," Caldwell said.

Wide receiver Calvin Johnson returned to practice after resting his ankle on Wednesday, and even though he was limited, he is on track to play Sunday.

The only player missing was defensive tackle Nick Fairley, who will miss his eighth straight game with a knee injury. Cornerback Mohammed Seisay, a special teams contributor, was a full participant for the second straight day despite a hamstring injury.

Although most teams practiced Tuesday to take Christmas off, Lions players chose to keep their typical routine. Caldwell said there was no change in the mood before practice despite working on the holiday.

"Like it always is," he said. "The guys have always been good and upbeat and focused, and it was the same thing today and that's hard to do this time of year."

Caldwell said he didn't celebrate Christmas on Wednesday night and arrived early Thursday morning as usual, watching film before practice. As Lions coach, Caldwell said he doesn't expect any presents this year.

"He doesn't need anything. Victories serve us well," Caldwell said.
