Gamble met Saturday with the New York Jets, who are looking to replace fired GM Mike Tannenbaum, sources said.
Gamble told the Jacksonville Jaguars he wasn't going to take a second interview for their GM job so he could concentrate on landing the Jets' position, sources said.
The Jets, though, are eyeing another GM candidate aside from Gamble, according to league sources.
New York Giants director of college scouting Marc Ross is scheduled to interview for the job on Monday, a league source said. He will interview for the Panthers GM job on Tuesday.
The Jaguars have narrowed their GM search to Falcons director of player personnel Dave Caldwell and Cardinals vice president of player personnel Steve Keim, sources said. Caldwell interviewed Friday with the Jets.
Shortly after the Jets fired Tannenbaum, they made a major push to interview and hire Ravens assistant general manager Eric DeCosta. Ultimately, they could not convince DeCosta to so much as interview for the job because he has a deal with Baltimore to be the successor to current GM Ozzie Newsome.
Gamble, the son of former Eagles president Harry Gamble, began his career in an entry-level position with the Eagles and worked his way up through the scouting and personnel ranks. He actually spent two seasons as a quality-control coach for the Jets under Rich Kotite (1995-96).
The Jets received a glowing recommendation on Gamble from former NFL executive and current ESPN analyst Bill Polian, who worked as the Colts' GM when Gamble was a college scout for the team.
Gamble has spent seven years with the 49ers, currently overseeing pro and college scouting under GM Trent Baalke, a former Jets scout.
