Jennings, 18, has been sidelined with a groin injury for the past month although he is responding to treatment ahead of this weekend`s tough trip to Brighton.
Yet Parry refuses to rush him back into action too soon and will not gamble on the player`s fitness.
Parry said: "Dale is still in rehabilitation and training. His condition is a little bit easier and we will assess how he is doing.
"But if we gamble on playing him on Saturday that could be at the expense of losing him for the rest of the season."
