James Walker reports that QB Carson Palmer is on the sidelines at Bengals practice today:

Cincinnati Bengals starting quarterback Carson Palmer will miss his second straight practice in training camp due to an illness.

Palmer was not participating at the beginning of Sunday’s 3 p.m. practice, as backups J.T. O’Sullivan and Jordan Palmer took reps with Cincinnati’s offense. The AFC North blog will have more on the Bengals from Georgetown later this evening.
