MILAN (AP) The presidents of Serie A clubs Lazio and Genoa plus Serie B's Bari are reportedly under investigation as part of an expanding inquiry into alleged collusion over Italian TV rights.

Italian daily Corriere della Sera reports that Genoa owner Enrico Preziosi and Bari president and former referee Gianluca Paparesta are being investigated by prosecutors in Milan for accepting illegal payments from Serie A's TV rights adviser Infront in order to register their clubs with league authorities.

Corriere says Lazio president Claudio Lotito is being investigated for obstructing the work of watchdog body Covisoc.

The heart of the scandal centers on Infront and the president of its Italian division Marco Bogarelli, who is reportedly under investigation for fixing a deal between Sky, Mediaset and clubs for the 2015-18 live domestic rights.
