The first team squad and management team were at Fratton Park on Monday for the annual Player Sponsors' Evening.
Players and staff mingled with fans in the Victory Lounge, also posing for photographs and signing autographs.
Each sponsor was then called up individually to collect a signed shirt from their chosen Blues star.
IMS and Pentland Plumbing were not present on the night to meet the players they sponsor – Chaplin and Stuart O'Keefe respectively.
Christian Oxlade-Chamberlain was also unable to present his shirt to European Pipeline Engineering Ltd after breaking his leg in training earlier in the day.
