A person informed of the move tells NFL Media Insider's Ian Rapoport that Martin was placed on the non-football illness list Saturday. ESPN's Field Yates first reported the move, which later appeared on the NFL's official transactions list Saturday.
A player can return from the NFI list in the event of a substance-abuse issue. Since that is not the case with Martin, he will not be eligible to play again this season.
Look for the team to shop the 2012 second-round draft pick in the offseason. Regardless of public sentiment, Martin will be a tough sell in NFL locker rooms.
The two potential landing spots that make the most sense are the Indianapolis Colts and San Francisco 49ers. Indianapolis is now home to his Stanford offensive coordinator (Pep Hamilton) and teammates Andrew Luck, Coby Fleener and Delano Howell. San Francisco has a similar setup with the support of Martin's former college head coach (Jim Harbaugh) and a handful of Stanford alumni on the roster.
Going to a team with strong leadership would be a welcome change for Martin.
