New Orleans Saints running back Mark Ingram has appealed his four-game suspension for violating the NFL's policy on performance-enhancing drugs to an arbiter, whose decision is due by May 16, his agents said Wednesday.
"At the end of the 2017 season, as a result of a NFL mandated random drug test, Mark Ingram tested positive for a substance that was not a performance enhancing substance, nor an illegal substance, but a substance in fact permissible with the proper use exemption with the NFL," agents Paul Bobbitt and David Jones said in a statement.
