Bears quarterback Caleb Williams uncertain about Sunday return after hamstring tear

Caleb Williams has participated in two full practices this week as he works toward a possible return, but he told reporters on Thursday that he does not yet know if he will be available for Sunday’s game against the Atlanta Falcons.

Williams, who suffered a hamstring injury during a red-zone scramble in the fourth quarter of the Bears’ 9-3 loss to the Minnesota Vikings on Sept. 20, said he felt a "pop" and looked back, noting that no one appeared to have grabbed him. He clarified that the injury is a hamstring tear rather than a strain, and that he must pass a series of medical checkpoints, including a stress test, before being cleared to play.

"Before you start asking, I do not know if I’m playing yet," Williams said in his first media appearance since the injury.

"It was a hamstring tear, and a pretty serious one," he added, while declining to disclose the specific grade of the tear.

Williams indicated that earlier reports describing the injury as a Grade 2 strain were inaccurate and that the grade assigned by medical staff would not be released publicly at this time.
