Chelsea's Terry has further tests

Adjust font size:

LONDON, England -- Chelsea captain John Terry has had to undergo a second brain scan after the sickening injury that saw him knocked out cold in the League Cup final win over Arsenal on Sunday.

Terry, whose season has been blighted by injury, made a remarkable recovery after being caught accidentally by Abou Diaby's full-blooded kick.

After discharging himself from hospital, the England international captain returned to the Millenium Stadium to celebrate with team-mates.

But he subsequently revealed that he had no memory of most of the match and media reports claim that the 26-year-old has suffered from unusual fatigue, headaches and dizziness since the accident.

A statement from the Premier League champions on Thursday read: "We stress that the scan was entirely routine and normal procedure for an injury of this type and raised no cause for concern."

Chelsea face Portsmouth in the Premiership on Saturday and FC Porto in the Champions League on Tuesday.

Terry, the lynchpin of the Chelsea miss, was sorely missed as he struggled with back and calf injuries either side of the New Year, with Jose Mourinho's men falling behind Manchester United in the title race.

Terry is also battling to be fit for crucial Euro 2008 qualifiers with England in Israel and Andorra later this month.
