Buffalo Bills quarterback Josh Allen is asking for prayers for Damar Hamlin as he remains in critical condition after suffering cardiac arrest during their game Monday night.

"Please pray for our brother," Allen tweeted late Monday.

Allen's support comes as the family of Hamlin asked fans to keep the NFL player "in your prayers."

In a statement shared Tuesday morning, Hamlin's family said they will share updates on the 24-year-old "as soon as we have them," and thanked fans and medical personnel for their help.

"On behalf of our family, we want to express our sincere gratitude for the love and support shown to Damar during this challenging time," they said in the statement, which was shared by Hamlin's friend and marketing rep Jordan Rooney. "We are deeply moved by the prayers, kind words, and donations from fans around the country."
