Zach Line

The New Orleans Saints have signed veteran fullback Zach Line, according to Line's agent, Mike McCartney. 

Line, the former SMU running back who spent the past four years in Minnesota blocking for Adrian Peterson, replaces John Kuhn, who tore his bicep last week in practice and was forced to go on injured reserve. 

The Saints got a closer look at Line at the end of training camp. 

New Orleans also brought in linebacker Gabriel Martin, who played eight games with the Arizona Cardinals last season, his only season in the NFL.
