Coby Fleener's concussion must have been extremely mild.
After reports came out on Tuesday that Fleener had missed practice due to a concussion, a day later he is back on the practice field and in full pads, according to George Bremer of the Anderson (Ind.) Herald-Bulletin.
Fleener's quick return is good news for the Colts, who were down to just two healthy tight ends.
