Everett was later placed on Washington's reserve/non-football injury list, concluding his season, and he tweeted on Thursday, "Thank you for all of your prayers, continue to pray for Olivia's family and me. Thank you all #Live4Liv."
An investigation into what caused the crash is still ongoing. Everett's attorney, Kaveh Noorishad, said Wednesday the football player is cooperating with law enforcement as the probe continues.
"At this time we ask that you respect the privacy of the individuals and families involved," Noorishad said, "and reserve judgment until all of the facts are gathered."
