Coach Marc Trestman didn’t name a starting middle linebacker for the season opener Sunday against the Cincinnati Bengals at Soldier Field. But it’s likely that veteran D.J. Williams will start and rookie Jon Bostic will relieve at some point. Williams participated fully in practice all week but missed more than four weeks before that with a calf injury. His conditioning will be monitored closely, with Bostic likely to step in at some point. Last year, Brian Urlacher missed most of training camp while recovering from a knee injury and was limited to 29 plays in the first half of the opener against the Colts. ‘‘I believe [Williams will] play,’’ Trestman said. ‘‘How much he’ll play will be relative to game-like conditions where it’s physical out there and we’re running sideline to sideline. He’s in good condition, I don’t know that he’s in great condition. I don’t know if we’ll know until we see whether he can take a significant amount of action.’’ Source: Chicago Sun Times
