The Seattle Seahawks postponed a workout for free-agent Colin Kaepernick this week after the quarterback declined to stop kneeling during the national anthem, a source told ESPN's Adam Schefter.

Seattle apparently contacted Kaepernick two weeks ago to arrange a visit, and the team is still considering bringing him in for a tryout, as no decisions are final, Schefter added.

The Seahawks reportedly wanted to know the former 49ers' signal-caller wouldn't kneel in the upcoming season, and he was unwilling to make that promise.

The news comes just one day after Cincinnati Bengals owner Mike Brown reportedly initiated a discussion with Eric Reid about national anthem protests during his free-agent visit with the team.

However, NFL Network's Ian Rapoport reported Kaepernick's visit was not postponed because he declined to stop kneeling, but rather his lack of plans regarding how to handle his protests.

Kaepernick has received little interest since he became a free agent after the 2016 season, with no workouts scheduled before the Seahawks' reported interest. Seattle doesn't have a backup quarterback on their roster.
