Chelsea's John Terry will not be fit to face Porto in the home leg of their Champions League tie on Tuesday.
Terry hurt his ankle in the first leg and now has a head injury
The match is poised at 1-1 but the Blues captain, 26, is still recovering from the head injury he sustained in his club's 2-1 Carling Cup victory.
Terry was accidentally kicked in the face by Arsenal's Abou Diaby during the final in Cardiff which Chelsea won 2-1.
"JT to play against Porto? No chance," said Blues manager Jose Mourinho. "The man is before the player."
Mourinho was speaking after the Premiership victory over Portsmouth and added: "JT is more important than a football result and we don't risk him.
"The medical rules are the medical rules."
Terry lost consciousness and was carried from the field by stretcher, then taken to the University Hospital of Wales after the second-half incident on Sunday.
But by 1800 GMT he was back at the stadium and able to celebrate the win having been checked over but the discharged.
The England captain had only just recovered from damaged ankle ligaments, which he suffered in the first leg of the Champions League tie against Porto, to play in the final.
He was carried off seven minutes into the draw in Portugal but recovered quicker than medical staff expected.
Mourinho said Terry could make his latest comeback against Tottenham in the FA Cup quarter-final on Sunday 11 March.
Meanwhile, Terry has spoken of his desire to one day become coach of the England team.
Terry, currently England captain, told the Daily Star: "I'm sure there isn't a man in England who wouldn't want to be England manager.
"Picking the team would be great and winning the World Cup unbelieveable."
