Delta Airlines says a charter flight carrying the Oklahoma City Thunder from Minneapolis to Chicago apparently encountered a bird early Saturday when it was landing, causing damage that prompted some players to post photos on social media showing the caved-in nose of the plane.

Carmelo Anthony, Josh Huestis, and Steven Adams all posted photos of the plane shortly after it landed around 12:45 a.m.

Anthony wrote on Instagram , “What possibly could we have hit in the SKY at this time of night? Everyone is Safe, Though.”

Hey @NASA @neiltyson @BillNye

We had a rough flight to say the least. 30000 feet in the air.

Delta Airlines spokeswoman Elizabeth Wolf said maintenance was evaluating the situation and that the damage was likely caused by a collision with a bird. She said the Boeing 757-200 landed safely without incident at Chicago’s Midway International Airport.

A spokesperson for the team told The Oklahoman newspaper that all of its players, staff and coaches were safe. The Thunder lost to the Minnesota Timberwolves 119-116 on Friday night. Oklahoma City plays the Chicago Bulls on Saturday night.
