Director of rugby Graham Dawe has been casting his eye over a host of prospective signings over the past few days as he tries to rebuild Albion’s squad.
Giant forward Collier spent three seasons at Albion between 2009 and 2012.
However, since then the former London Welsh and Manchester player has not played much professional rugby.
He spent the 2013/14 season at Ealing in the Championship but only made six appearances for them.
Dawe, though, clearly believes he is worth having a look as he attempts to add some experience to a young squad.
“Dan’s come down for a week’s training,” admitted Dawe when asked about the lock’s presence at Brickfields.
“I spoke to him last week with a view to possibly re-joining Plymouth, but no decision has been made.”
Albion have so far confirmed 17 players for next season’s National One campaign but Dawe does hope to complete deals with around four more this week. However, he will also continue to look at trialists over the next few weeks.
Meanwhile, ambitious Darlington have now confirmed that wingers Jake Henry and Peter Homan have joined them from Albion. Prop Tom Harrison has also moved there, while Camborne have announced that Sam Matavesi will join them for the start of the 2015/16 campaign.
