Yes, Packers quarterback Aaron Rodgers practiced on Wednesday, just as he's done for at least part of the past two weeks, but that still doesn't mean he's been medically cleared for action.
From Rob Demovsky of ESPN.com:
QB Aaron Rodgers took snaps with backup OL JC Tretter. Matt Flynn worked with starting center EDS. Same routine as last few weeks. #Packers

Flynn taking snaps from Evan Dietrich-Smith in all likelihood indicates the Packers are still preparing as if Flynn will be the starting quarterback, at least for the time being.
Things could change as early as tomorrow or even as little as a few minutes down the road, because it's important to note that the media is only allowed to watch individual drills before being asked to leave.
Last week, Rodgers also took snaps with the backup center before it was later learned he got work with the first-string offense during the team portion of practice, which the media did not see.
Wednesday represents just the first day of practice this week, so there's still time for Rodgers to increase his workload later this week as the team prepares to face the Pittsburgh Steelers this upcoming Sunday with an opportunity to remain alive in the fight for a playoff berth.
Mike McCarthy will offer and update during a press conference in the afternoon, and Wednesday is typically the day Rodgers meets with the local media, perhaps allowing for an opportunity to shed more light into his injury situation in coming back from a broken collarbone.
UPDATE: Rodgers will reportedly not meet with the media until Thursday.
