Denver Broncos quarterback Joe Flacco is expected to miss 4-6 weeks because of a neck injury, pending reviews from doctors, a source tells ESPN's Adam Schefter.
Flacco received a second opinion on the bulging disc in his neck and, a source tells Schefter, will not need surgery, pending reviews from Dr. Robert Watkins in Los Angeles and Dr. Jack Kelley in Connecticut.
The Broncos have announced that Flacco will miss Sunday's game against the Cleveland Browns but have not yet disclosed an official timeline for his return. Initial reports indicated that the former Super Bowl MVP could miss the remainder of the season, depending on the medical evaluations on his neck.
