At the San Francisco 49ers' ribbon cutting ceremony for Levi's Stadium, Roger Goodell broached the possibility of the Oakland Raiders also sharing the facility.

Goodell said it's up to the Raiders to decide whether they want to try to build a stadim in Oakland or share the facility in Santa Clara.

Raiders owner Mark Davis has said he doesn't want to be a renter in the 49ers' facility, which is now fitted with red seats and posters of past and present San Francisco greats.

"They have to make that determination, whether they're in a new stadium in Oakland or whether they feel that it's best to join this stadium," Goodell said, according to the Bay Area Sports Guy, who tweeted the commissioner's remarks. "We're working on that, and that's one of the decisions they'll have to make."
