Some of the Detroit Lions’ best days and happiest memories involved Barry Sanders and Moore. Back then, Moore wore jersey number 84 — and he’s using that as the basis for his special Salvation Army promotion.

“Donations can be made in increments of $84, $840 and the for first person to donate $8,400, I’ll sign an authentic throwback jersey of mine from 1996 as a token just to say ‘Thank you for their generosity and support for this cause,’” Moore said.

Metro Detroit’s charitably-minded are standing by Moore’s side in this.

Salvation Army Major Timothy Meyer has another incentive for people to get involved.

“We are so blessed that an anonymous donor is also doubling all the income during this $84,000 Challenge,” Meyer said. “It’s a really good opportunity for people to stretch their donation to the Salvation Army.”
