Mike Garafolo of NFL Network reported the Seahawks' talks with Kaepernick are in a "holding pattern," but nothing has been decided.
Davis, 28, agreed to a one-year contract for the veteran's minimum. A 2012 undrafted free agent, Davis has not thrown a pass since the 2015 season.
Kaepernick, 30, went unsigned last season despite throwing for 2,241 yards and 16 touchdowns against four interceptions during the 2016 campaign with the San Francisco 49ers. His national anthem protests appear to be the overarching cause of his continued unemployment. Kaepernick has sued the NFL claiming its owners colluded to keep him out of the league.
ESPN's Adam Schefter reported the Seahawks pulled out of a workout because Kaepernick refused to say he would not kneel during the national anthem. The report says it was a last-minute request from Seattle, which to that point had planned to bring him in for a tryout.
The Seahawks brought Kaepernick in for a meeting last year before declining to sign him. Seattle and the Baltimore Ravens are the only teams that have come close to adding the 49ers' former franchise face since he became a free agent.
Adidas has expressed interest in signing Kaepernick to an endorsement deal if he's signed by an NFL team.
“We love athletes that have a platform to make the world a better place,” Adidas president Mark King said, per Greg Moore of AZCentral. “If they’re an activist in a way that brings attention to something that moves the world forward, even if there’s controversy at that moment, we’re really interested in those athletes because I think it represents the world today.”
Owners and general managers from multiple NFL teams have already given their depositions in the Kaepernick collusion case. The league's owners have said their refusal to sign Kaepernick was made individually rather than as a collective.
