The Redskins appear to have fallen behind Wednesday in the race to sign free agent cornerback Antoine Winfield.

The Seattle Seahawks were making a strong push to sign Winfield and seemed poised to get a deal completed, a person with knowledge of the negotiations said.

The person added, however, that the Minnesota Vikings remained in the bidding for Winfield.

It was not clear late Wednesday if the Redskins had been eliminated from consideration.

The Redskins appeared to remain interested in Winfield even after re-signing DeAngelo Hall, one of their starters at cornerback last season who had been released just before the free agent market opened. The Redskins, who ranked 30th in the NFL in pass defense last season, also have holdover starter Josh Wilson and added free agent cornerback E.J. Biggers from the Tampa Bay Buccaneers. They could select a cornerback early in this month’s NFL draft.

Winfield was released by Minnesota earlier this offseason. The Vikings remain interested in re-signing him. But Winfield visited Seattle this week and the Seahawks were attempting to team him with their highly acclaimed starting cornerbacks, Richard Sherman and Brandon Browner. ESPN reported earlier Wednesday that the Seahawks were close to finishing a deal with Winfield.

The Redskins’ pursuit of Winfield came even amid their tight salary cap situation. As of Tuesday, they were only about $30,000 under the salary cap. So adding Winfield would require the Redskins to make a move to clear salary cap room.
