‘Less than a year after inking a seven-year deal with Buffalo and earning first-time All-Star honors, Okposo missed the final two weeks of the 2016-17 season with what the Sabres called a “very concerning” illness. The issue actually resulted from a concussion suffered at practice, as The Athletic later reported, and left Okposo hospitalized in a neurosurgical intensive care unit following suicidal thoughts. The forward also missed a week of action in March 2018 with a separate concussion.’
