According to a statement on the club's official website, Pirates have suspended Leal as they "embark on a fact finding investigation".
The club is looking for "reasons why during performance evaluation sessions, the coach expressed that 'he could not see his way forward” and offered the chairman “to do what is right for the club'.
"Augusto Palacios, technical director of development will assume the role of head coach. The rest of the technical team stays the same," the terse statement concludes.
The news is not good for Bucs ahead of their Soweto Derby meeting with Kaizer Chiefs on the weekend.
