Tank Johnson had already had an eventful off-season for the wrong reasons, but the defensive tackle could miss the start of the season because of an injury.
had surgery last week to repair a torn quadriceps, which he suffered away from Halas Hall. The rehabilitation is expected to take four to six months, which puts his status for the beginning of the season in doubt.
After finishing fourth in the team with 5.0 sacks in a reserve role, Johnson was expected to challenge Ian Scott for a starting job.
The six-foot-3, 300-pounder was arrested twice in the span of eight months, the second of which came in February for aggravated battery and resisting arrest. However, the charges were eventually dropped when the arresting officer opted not to pursue the case. The NFL could still pursue disciplinary actions.
The top reserves behind Johnson are Alfonso Boone, Israel Idonije and possibly Michael Haynes. The Bears may turn to the draft or look for depth on the free agent market.
