Coach Joe Philbin has maintained a policy of not disclosing any information relating to injuries. Hartline worked with trainers in the early part of practice.
Philbin declined Wednesday afternoon to explain wide receiver Mike Wallace being kept out of the scrimmage Monday, but Wallace was practicing Wednesday night.
Rookie cornerback Jamar Taylor, a cornerback taken in the second round, returned to practice for the first time since July 22, but on a limited basis.
