Harris (concussion) returned to practice Tuesday, Andrew Callahan of Boston Herald reports.
After sustaining a concussion in Week 9 at Carolina, Harris didn't practice last week and ultimately was ruled out ahead of this past Sunday's game versus the Browns. He also was listed as a non-participant on Monday's estimated injury report, so Tuesday's appearance marks the first indication of progress through the protocol for head injuries. Harris' activity level will be known later Tuesday, but he still must receive clearance from an independent neurologist to be able to suit up Thursday in Atlanta.
