DAVIE, Fla. — Quarterback Chad Pennington was added to the Miami Dolphins' injury report because of a sore foot, and he's listed as probable for Sunday's game against Oakland.

The Dolphins didn't elaborate on the injury Sunday or say or when it happened. Pennington ranks sixth in the NFL in passing and has led surprising Miami to a 5-4 record.

If Pennington can't play, rookie Chad Henne would make his first NFL start. He was taken in the second round of the April draft.

The Dolphins signed linebacker Rob Ninkovich off their practice squad and placed guard Matt McChesney on injured reserve.
