The Denver Broncos will be without Joe Flacco for 4-6 weeks, according to a source.

Flacco received a second opinion on the bulging disk in his neck and will not need surgery after reviews from two doctors.

"Everything is still on the table with Joe," coach Vic Fangio said. "We can leave him on the 53[-man roster] and wait a while, or we could IR him. We'll make that decision here in the next couple days. ... By the end of the week I think we'll have a better understanding, after getting all of the medical advice, going over it, what plan we'll take long term."
