NCAA spokesperson Stacey Osburn said Friday such gag orders usually are extended to schools under investigation.
"According to NCAA rules, all parties of the investigation must maintain the confidentiality of interviews to protect the integrity of an investigation," she said. "This includes the school and enforcement staff."
LSU admitted to paying Lyles $6,000 last season, and in return received scouting information and, potentially, inappropriate access to high school recruits. A Thursday press release from the athletic department confirmed that an NCAA official had been in Baton Rouge interviewing unidentified members of the coaching staff about Lyles' connection with the program.
