Vincent has missed much of Vale's run-in after suffering an ankle injury last month but the winger looks set to be included in the squad that travels to Adams Park for the final game of the season.
"We thought Ashley would be in the squad for Northampton last week, but he wasn't quite right on the Friday before the game," said Adams, whose side clinched automatic promotion with a 2-2 home draw against the Cobblers last Saturday.
"We'll play it by ear, but I hope he can play because he's been a massive part of it this season."
Joe Davis might have got a run out against Wanderers but the young defender limped out of a reserve-team game on Tuesday afternoon and has been ruled out through injury.
He will join striker Calvin Andrew (knee) and versatile midfielder Rob Taylor (Achilles) on the sidelines.
Midfielder Kingsley James and centre-half Clayton McDonald will both travel after returning from loan spells with Hereford and Bristol Rovers respectively, but the latter has a hamstring injury.
