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.¡±

During the first quarter of the Bills¡¯f game against the Cincinnati Bengals, Hamlin got to his feet after making a tackle and then collapsed.

After having his heartbeat restored on the field as stunned players from both teams cried, prayed and hugged, an ambulance took Hamlin to University of Cincinnati Medical Center.

U.S. President Joe Biden, speaking to reporters in Hebron, Kentucky, on Wednesday, said Hamlin¡¯s collapse was not a sign the NFL has become too dangerous, while noting the inherent risk of a sport with violent collisions on nearly every play.

¡°I think working like hell on the helmets and the concussion protocols, that all makes a lot of sense. But ... it is dangerous. We¡¯ve got to just acknowledge it.¡±

The Bills offered no further details on Hamlin¡¯s condition, but his friend and business partner Jordon Rooney told ESPN earlier on Wednesday that doctors saw promising readings overnight that they had hoped to see by Wednesday morning.

Rooney did not reply when asked by Reuters to provide details on Hamlin¡¯s condition.

Earlier on Wednesday, the Bills held meetings and a walkthrough ¡ª a slower-paced practice in which players typically do not wear pads and go through plays without physical contact ¡ª but did not provide any media availability.

The team¡¯s game against the Bengals was postponed on Monday after Hamlin collapsed on the field.

The NFL, whose regular season concludes on Sunday, has said the Buffalo-Cincinnati game would not resume this week.

During a conference call with reporters on Wednesday, NFL Executive Vice President of Communications Jeff Miller said the conversation about what to do about the game has started and a decision will be made in the coming days.

The game, if played, would have playoff implications for both teams as they are battling with the Kansas City Chiefs for the top seed in the AFC, which comes with a first-round playoff bye.
