The Buffalo Bills said on Wednesday that safety Damar Hamlin has shown "signs of improvement" since suffering a cardiac arrest during a Monday night game in Cincinnati, but that he remains in critical condition.
"Damar remains in the ICU (intensive care unit) in critical condition with signs of improvement noted yesterday and overnight," the Bills said in a social media post.
"He is expected to remain under intensive care as his healthcare team continues to monitor and treat him."
