The 22 year central defender is the cousin of Liverpool midfielder Steve Gerrard.
Gerrard (Anthony) is said to have agreed terms today in Cardiff and is due to complete a move after having a medical.
Scunthorpe had offered £200,000 to Walsall but that offer was rejected.
Gerrard started as a trainee for Everton before moving to Walsall where he's played for the last 4 years.
