TEMPE, Ariz. -- Arizona Cardinals safety Rashad Johnson is expected to return to the field Sunday, two weeks after losing the tip of his left middle finger during a game Sept. 22 against the New Orleans Saints.

Johnson was cleared by team doctors Thursday and was listed as questionable in Friday's injury report. Like last week, he practiced Friday after sitting out Wednesday and Thursday.

"It's just a matter of how much he can function with the cast on," coach Bruce Arians said.

Johnson was injured during a special teams play late in the first half against the Saints. After the play, he noticed his glove was bloody, and when it was cut off, the bone was exposed while the fingertip remained in the glove.

Johnson left the game and did not return.

There was hope he could have played Sunday against Tampa Bay, but the chance of infection was too great and Arians didn't want Johnson to risk further damage to the finger.

The Cardinals (2-2) play host to the Carolina Panthers (1-2) on Sunday.
