The Packers public relations staff confirmed Monday night that Favre was at Lambeau Field working out in the morning, but was excused from practice by McCarthy.
Favre wasn't the only player missing in action on Monday. Cornerback Ahmad Carroll missed Friday's practice for personal reasons and McCarthy said he expected him back on Sunday, but Carroll was not at Monday's practice.
Cornerbacks Al Harris and Charles Woodson, defensive tackle Ryan Pickett and fullback William Henderson also missed Monday's practice. Harris, Woodson and Pickett have yet to make an appearance at the OTAs, but Henderson practiced on Thursday and Friday last week. Linebacker A.J. Hawk is not eligible to practice until he is finished with his college final exams, which means he will likely arrive later this week.
