Wheaton suffered a groin injury two weeks ago and hasn’t practiced since. With the Bears in need of help at receiver, the team traded a conditional seventh-round to the Chargers in exchange for Dontrelle Inman.

The Bears’ injury report was lengthy Wednesday, with guard Kyle Long as the most notable absence. Long was taking a maintenance day to rest his surgically repaired ankle, coach John Fox said.

The Bears (3-4) take the practice field again Thursday in preparation of Sunday’s contest with the Saints (4-2) in New Orleans.
