The duo has entered into the final six months of their respective contracts with negotiations regarding contract extensions expected to commence imminently.
With limited game-time so far this season, Sandilands' future at Pirates remains uncertain.
While Jele continues to prove a pivotal member of the squad, although the 35-year-old has suffered a spate of recent injuries.
Pirates legend Edward 'Magents' Motale has now urged the club to not make any knee-jerk decisions regarding the experienced duo.
"With overseas-based teams, we still see players active at 38-years-old, what matters is performance and results that's all.
"As long as a player performs I would retain and sign him, the chairman must consult with the coach and he will tell him what he thinks of the past few matches these two players have played.
"If there remains potential, and whether there is a future for them at the club.
"Remember the chairman is not always with the team so he must ask the coach who should be staying and who should be leaving, based on performance. Age doesn't say anything.
"Happy was doing well until he got injured, Sandilands never played I think over the previous two seasons now, so I can't say anything on performance because he never played."
