The Bears today promoted offensive lineman Edwin Williams from the practice squad and released Johan Asiata.
If Asiata clears waivers, he will likely be added to the practice squad but that may not be a given, since teams around the league are struggling for depth on the offensive line.
Asiata started training camp at left guard, but his starting spot was quickly claimed by Lance Louis, a 2009 seventh-round pick who moved to right guard. That left veteran Roberto Garza to swing to left guard.
Williams played center at Maryland but has also played in the NFL at guard. His versatility was a key to the decision.
