The Tigers appear in no rush to confirm senior list contracts for rookies Jason Castagna and Jayden Short, who look certain to be elevated at the end of the season.
Short, 20, has played nine games this season and averaged 16 possessions across the past four weeks since being recalled to the team in a half-back role.
Castagna, meanwhile, has played three games but is highly-rated and was among the team's best in its 10-point loss to the Western Bulldogs last Saturday.
The second-year pair, who came through the Northern Knights under-18s, are best mates and are both managed by former Tiger Will Thursfield.
It is understood the Tigers will wait to see more senior-level football from both before confirming senior-list contracts.
