The Broncos cannot comment on or confirm the reported trade.
Any reported trade — and the corresponding compensation — cannot be made official until the new year begins on March 13.
According to reports, the Broncos are likely to send a fourth-round pick to Baltimore. Denver currently owns two fourth-round selections. They accrued an extra fourth-rounder in October when they traded wide receiver Demaryius Thomas to the Houston Texans.
The Delaware product has won 106 career games — including postseason appearances — and thrown for 212 touchdowns and more than 38,000 yards. He has started all 16 games in nine of his 11 seasons as a professional.
Flacco's finest moments came at the end of the 2012 season as he threw 11 touchdowns and zero interceptions in the postseason to guide the Ravens to a Super Bowl XLVII title. He was named Super Bowl MVP following a three-touchdown, zero-interception performance in a win over the 49ers.
Flacco has a 10-5 career postseason record.
The 11-year veteran played in nine games in 2018 — including a Week 3 matchup against the Broncos in Baltimore — before he suffered an injury that forced him out of the lineup. He threw for 2,465 yards, 12 touchdowns and six interceptions while completing 61.2 percent of his passes. Before the injury, Flacco was on pace to set career bests for most passing yards and fewest interceptions.
Flacco was cleared later in the year, but the Ravens chose to start rookie quarterback Lamar Jackson.
The Ravens drafted Flacco with the 18th-overall pick in the first round of the 2008 NFL Draft.
Case Keenum — the Broncos' starter in 2018 — and Kevin Hogan both remain on the Broncos' roster.
