Stafford tweeted a similar message Thursday after telling reporters Tuesday at University of Georgia's pro day -- he attended the school before going No. 1 overall in the 2009 NFL Draft -- that he is recovering well and rehabilitating in Birmingham, Ala., with therapists from Dr. James Andrews' office. Andrews performed the surgery on Stafford's right shoulder in January.
The Lions can receive reports on Stafford's progress, but they aren't permitting to make contact with him during the lockout.
Stafford played in just three games last season after playing in 10 as a rookie.
