A day after the confirmation that Ciaran Byrne and Cillian McDaid have returned to Ireland following stints in the AFL with Carlton, Collingwood have announced the double signing of two more highly promising Irish talents.

Anton Tohill - son of Derry great Anthony - and Corkman Mark Keane are heading to Melbourne having impressed in the AFL Combine in UCD last December.

They followed that up with further trials at the AFL Academy in the US and have been snapped up having  showed tremendous potential.

Byrne and McDaid are back in their home counties of Louth and Galway respectively but all possibilities are laid out before Tohill and Keane as they look to crack it Down Under.

They have spent the last year under the watch of ex-Down footballer Marty Clarke, who played 73 times for Collingwood in two stints with the Melbourne club. 

In the late 1980s, Anthony Tohill spent a short time as a rookie player with the Melbourne Demons in the AFL.

"Mark and Anton will really add to our developing key position depth," Collingwood recruiting manager Derek Hine told the club website.

"They are different to each other in the manner in which they play. Anton has the makings of a tall utility who will be capable at both ends of the ground, with the potential to play minutes in the ruck.

"Mark is very strong overhead and has natural game sense. We can see him playing as a key forward or key defender." 

Keane and Tohill will head for Australia next month.
