IOWA CITY, Iowa (AP) – The president of the Iowa Board of Regents says he was briefed last summer about possible NCAA violations at Iowa State University but he doesn’t consider them serious.  Craig Lang said Thursday that he and Regent Bruce Rastetter were informed by ISU President Steven Leath about the investigation involving impermissible calls to recruits.

He says Leath told them the main issue was that coaches didn’t know they were supposed to document calls that failed to connect with recruits because they were dropped or not answered.  Lang says he recalls thinking “obviously, this isn’t serious.”

Iowa State announced Tuesday an internal investigation found 79 improper calls between 2008 and 2011, and 1,400 calls that should have been documented. It has asked the NCAA for two years of probation as punishment.

KANSAS CITY, Mo. (AP) – The Kansas City Chiefs added depth at linebacker Thursday by signing Frank Zombo, who had spent the past three seasons with the Green Bay Packers. Zombo will be reunited with longtime Packers personnel man John Dorsey, who was hired as the Chiefs’ general manager in January and has been aggressively overhauling the team’s roster.

A former undrafted free agent, Zombo played college football at Central Michigan before signing with Green Bay. He played in 25 games and made nine starts, racking up 53 tackles and five sacks while forcing a pair of fumbles while dealing with several injuries.

On Wednesday, the Chiefs signed reserve offensive lineman Tommy Draheim, who spent time with the Packers in training camp last season.
