SAINTS have made two injury-forced changes to the 21 man squad ahead of Friday's clash with Huddersfield at Headingley Stadium (6pm).
Young hooker Josh Eaves comes into the squad in place of James Roby, who misses out after picking up a head knock on Sunday.
Aaron Smith is also included, so Saints have options to cover the nine role.
Joe Batchelor comes into the squad, with Zeb Taia failing to recover from his minor groin strain.
Dom Peyroux, who returned last week, will slot into the second row in Taia's place.
Theo Fages is named despite a knee injury, with Woolf explaining it has recovered well.
Teen half Lewis Dodd, however, will be on standby if needed.
