Baltimore Ravens head coach John Harbaugh and general manager Ozzie Newsome support the signing of free-agent quarterback Colin Kaepernick, but have met resistance from owner Steve Bisciotti, sources tell ESPN's Dianna Russini.
Sources say this is not the first time an NFL team has wanted to add Kaepernick to its roster, but the move was blocked by the team's owner.
Kaepernick's name came up last week after Harbaugh said starting quarterback Joe Flacco would miss a week with a back injury. Backup Ryan Mallett has struggled while filling in with the first-team offense, throwing at least five interceptions during one practice.
On Sunday, Bisciotti said the team was still weighing whether to sign Kaepernick, who drew national attention last season when he knelt during the national anthem before games to protest social injustice, which sources have told ESPN he will no longer do in 2017.
