Reading have confirmed that new signing Matej Vydra will wear the No.7 shirt while at the Madejski Stadium.
Czech forward Vydra joined the club on the last day of the transfer window on a season-long loan from Watford.
The number seven shirt was previously worn by Pavel Pogrebnyak before his departure to Dynamo Moscow last month.
Fellow new signings Lucas Piazon and Ola John will wear the No.17 and 20 shirts respectively.
The No.20 shirt was worn by three players last year - Alex McCarthy before he left for Queens Park Rangers, Glenn Murray while on loan at the club, and Yakubu when he joined in February.
