The Miami Dolphins are now four players under the roster limit.
They didn't need to make any cuts Wednesday to get down to 75 players because they had only 72. They were looking forward to the big scavenger hunt after teams reduce their rosters to the 53-man regular-season allotment Saturday afternoon.
Davis' agent, Curtis Stephens, phoned ESPN.com to rebuff a report that laid out suspicious circumstances surrounding the move.
"The truth of the matter is there was an opportunity for Keith with the Dolphins, and it didn't work out," Stephens said. "Players are signed and released every day in the NFL. It was just another transaction. There's no police blotter. He's not in anyone's doghouse.
"There's nothing to this story other than it's a transaction that reflects a situation that didn't work out."
The Dolphins signed Davis on March 11. They were familiar with his work. Dolphins football operations boss Bill Parcells coached him in Dallas. New head coach Tony Sparano and new GM Jeff Ireland also came from the Cowboys.
Davis was expected to be a major special-teams contributor for the Dolphins. He also was listed second on the depth chart at strong safety behind Yeremiah Bell heading into Thursday night's preseason finale against the New Orleans Saints.
Davis was tied for sixth with seven defensive tackles in the preseason, but he didn't have any on special teams.
