British heavyweight champion and Ipswich fan Fabio Wardley was spotted in the away end at Saturday's derby against Norwich City.
The 29-year-old Suffolk sensation, who is sponsored by his beloved Blues, and wears the club's colours and badge in the ring, watched Ipswich suffer a blow to their bid for automatic promotion to the Premier League with a 1-0 defeat.
It came days after Wardley drew with Frazer Clarke to retain the British and Commonwealth heavyweight championship.
After 12 breath-taking rounds on one card Wardley won 114-113, on another Clarke had it 115-112 and on the third they were level 113-113.
