The former Wakefield, Huddersfield and England prop, who was a member of the Rhinos' Grand Final-winning team in October, joined the City Reds on a month's loan after being unable to force his way into Brian McDermott's team so far this season.
Instead of lining up against Melbourne Storm in Friday's World Club Challenge, Griffin was preparing to make his Reds debut in Sunday's Super League televised match against Hull KR at the City of Salford Stadium.
"I've come to get some game time," he said. "If I can help the boys in any way, that's great."
The experienced Griffin will help bolster the Salford ranks while coach Phil Veivers waits for the arrival of reinforcements, initially in the form of Manly Sea Eagles duo Vic Mauro and Liam Foran, but he remains part of the Rhinos' future plans.
Meanwhile, Huddersfield look to maintain the only 100% record when they visit Wakefield, who bounced back from their heavy opening day defeat by Bradford to post back-to-back wins.
That makes the Wildcats dangerous opponents, according to the Giants' former Wakefield full-back Scott Grix.
"We have looked at the tapes of their games and they are definitely looking pretty sharp," said Grix, whose side will be on a high following their impressive win over Wigan.
"With the way we played at the weekend we don't want to get ahead of ourselves. It will be tough going over there and I know they will be ready for it."
Elsewhere, Wigan will be expected to return to winning ways when they host London Broncos, who have lost all three matches so far, and Castleford will be hoping to end a traumatic week on a high note when they host Catalan Dragons.
