Supernatural fan favorite and series regular Misha Collins was mugged and beaten up during his trip to the Supernatural Convention (MinnCon) in Minneapolis, Mn. Friday night, according to multiple accounts by attendees.

An outpour of the CW show’s fans sent well wishes to the actor on Twitter Saturday, one tweeter describing Collins’ badly-bruised lip: “Misha can’t smile. Misha Collins who’s smile lights up an entire room cannot smile because his lip is hurt so badly. Im so upset.”

The Misha, We Love You! Twitter account tweeted that Collins was mugged by four men: “Apparently four guys mugged him and beat him pretty badly. & he’s still there doing photo ops, bless him.”

Another Facebook user posted that actor and MC Richard Speight Jr. announced that Collins would miss his scheduled panel because of the events that took place: “Richard just came out to announce that Misha was mugged and beaten up last night. His panel has been cancelled, he’s still going to try to do photo ops as he can. I’m like … Freaking out right now I hope he’s ok.”

Richard Speight announced it. We’re sending him our love and support. #WeLoveYouMisha
