While all three trained well, it was Wells in particular who coach Brad Scott was most enthused about.
"Really good to have Wellsy back, he trained really strongly today (Thursday) and he's raring to go," Scott said in the Interactive Team of the Week video.
Grima and Wright will need to train well on Saturday in Perth to cement their places.
"We'll just put them through their paces, one final little hurdle to clear there. We expect them to take their place and they're important inclusions into our side," Scott said.
Cruize Garlett, Luke Delaney and Aaron Mullett are the unlucky players to make way and will be on standby as emergencies.
