Hamlin went into cardiac arrest and collapsed after tackling Cincinnati’s Tee Higgins on Monday Night Football.
“His heart had went out so they had to resuscitate him twice” his uncle, Dorrian Glenn, told CNN. “They resuscitated him on the field before they brought him to the hospital and then they resuscitated him a second time when they got him to the hospital.”
Glenn told ESPN there is also concern over lung damage.
In an optimistic note, Glenn shared with the sports network that his nephew was “improving from where he was yesterday.”
“I know he’s still here, I know he’s fighting,” Glenn said to ESPN.
Hamlin’s agent, Ron Butler, added that Hamlin’s oxygen levels have increased.
At last report, Hamlin remained sedated and in critical condition at a Cincinnati hospital.
