(Reuters) - Tabcorp Holdings Ltd <TAH.AX>, Australia's biggest horse racing and sports betting company, said on Thursday the Australian Competition Tribunal has extended its deadline to rule on Tabcorp's A$6.4 billion ($4.82 billion) deal to buy rival Tatts Group Ltd <TTS.AX>.
The Australian competition watchdog pushed out the deadline to Sept. 10, from June 13 previously, Tabcorp said in a statement.
Tabcorp agreed in October to acquire Tatts in an effort to fend off a growing challenge from overseas online rivals.
