To see back in training with the Mariners...

Bosnich played for the Mariners, who will make a "major announcement" this morningy, during a 3-0 Pre-Season Cup victory over Sydney last month.

If the deal is finalised, the former Australia international could line-up against Sydney at the Bluetongue Stadium on Saturday.

Bosnich, 36, was expected to agree a five-week contract with the Mariners to coincide with Danny Vukovic's five-week ban following his clash with a referee during last seasons A-League Grand Final in February.

But the deal is believed to have been extended to include this weekend's highly-anticipated match and the meeting with Wellington Phoenix on October 19 - the weekend after Vukovic's return.

Vukovic, 23, is still eligible on Saturday meaning there is no guarantee Bosnich will face Sydney.
