Conor Clifford sustained broken nose and concussion in Europa League tie
The Dubliner came on as a substitute in the 3-2 extra-time defeat to FK Riteriai on Tuesday night but was knocked out and then stretchered off the pitch following a nasty collision with his teammate, Colm Horgan during extra-time.
There was a long delay in the game and six minutes added on at the end after the incident as Clifford was rushed to hospital alongside club doctor, Noel Boyle and physio, Michael Hegarty.
"Conor had a real nasty injury and was completely knocked out," said Devine. "He was concussed, broke his nose and had a lot of stitches inside his nose.
"The healthcare system in Lithuania is of the highest order and Michael Hegarty (physio) and Noel Boyle (club doctor) did a brilliant job with him, got him to the hospital and got a cat scan and thankfully we were able to hold the plane and bring him back with us.
"He's in a lot of difficulties with his breathing and with the pain in his face and his head and we wish him the best in his recovery. Hopefully he's back up and going again as quickly as possible.
"He caught the back of Colm Horgan's head and it was a nasty injury. He's had no luck at all. He's been brilliant for us and probably hasn't played the games he'd like to play but hopefully we can get him back as soon as possible."
