Celtic's skipper Stephen McManus could play in their UEFA Champions League match with Benfica on Wednesday after getting the medical all-clear to travel.
McManus was a doubt for the crucial game in Lisbon after suffering a head knock during Celtic's 3-0 reverse to Rangers at Ibrox on Saturday.
He worryingly left the pitch on a stretcher wearing an oxygen mask after losing consciousness.
But he got the all-clear to travel on Sunday after spending Saturday night recovering at home after being released from hospital.
He will now join the rest of the squad at Glasgow Airport on Monday morning ahead of Wednesday's match.
A statement on www.celticfc.net said: "Doctors were happy with the results of the tests carried out on Stephen and his progress will be monitored by the Celtic medical team over the next few days."
Celtic go into the game - which will be screened live on Sky Sports Extra at 7.45pm - in second place in Group D with three points from their opening two games.
They will face a Benfica side desperate to win as they sit at the foot of the table with no points so far.
