According to a friend and business partner of the Buffalo Bills safety, doctors saw promising signs of progress overnight from Hamlin, who remains in critical condition.
Hamlin is in the intensive care unit at the University of Cincinnati Medical Center, less than a day after he went into cardiac arrest on the field, according to Rooney.
Rooney said that doctors had hoped to see promising readings from Hamlin by Wednesday, but they were not able to. Hamlin's agent told Jeremy Fowler that Hamlin's oxygen levels had gone up.
Hamlin collapsed on the field after making a tackle on the other side of the ball. According to the broadcast, Hamlin received oxygen as he was taken off the field after collapsing. The man was taken to the hospital.
There will be no media availability for the Bills on Wednesday.
The Bills-Bengals game won't be resumed this week, and the league isn't sure when it will resume. The regular-season schedule has not been changed.
