Harris, who was expected to provide a boost to Louisville's wide receiver corps this season, injured his knee earlier during practice Monday afternoon.
"Michaelee tore his PCL (posterior cruciate knee ligament)," Strong said after practice. "I don't know the timeframe when he'll be back. If he's not able to play he'll get a redshirt."
Harris, who is out of action indefinitely, was working in the wide receiver rotation before injuring his knee in a non-contact situation in the second practice on Monday. Practice Notebook
- Zed Evans,a 5'11, 183-pound redshirt freshman, has moved from cornerback to running back, where he's been practicing for the past few days. Team sources indicated he'll likely stay at his new position.
- Charlie Strong said there was no announcement on the quarterback front. "We're still working through it," he said. Adam Froman is the presumed frontrunner.
- Greg Scruggs, after missing Saturday's scrimmage, was back in action during Wednesday practice, which included scrimmage-type action with referees.
- Charlie Strong said he's seen improvement from his defense during fall camp. "Defensively there's a lot of progress we've made," Strong said. "This is our 14th practice today so there should be progress. There coming along, but they can get better."
- Freshman running back Kamal Hogan, who sustained a concussion in practice earlier in the week, is likely out for a while with the head injury.
- Freshman Marcus Smith, who came in as a quarterback, has been moved to outside linebacker.
- Four-star safety Demar Dorsey and running back Corvin Lamb are still awaiting clearance to join the team.
- Louisville will conclude two a days this afternoon.
