Adelaide’s salary cap scandal has deepened amid fresh allegations of secret payments for captain Nathan van Berlo.

The club, which confessed late in last month’s trade period that they had secretly brokered a third-party deal for Kurt Tippet, will front an AFL Commission hearing on Monday.

If the latest allegations, reported by Fairfax Media, are proved then the club will likely face a raft of sanctions. Several club officials also stand to lose their jobs.

The Tippett deal allegedly included payments from four companies.

South Australian-based resource company McMahon Services reportedly paid him $20,000 to $30,000 a year.

Balfours Bakery, for whom Tippett fronted a television commercial, paid the forward $30,000.

It is not yet known which company made payments to van Berlo.

The Crows were forced to delist untried utility Nick Joyce this week after being told that they could not delist Tippett ahead of Monday’s AFL hearing.
