The University of Maryland has self-imposed penalties that include limiting football practice time during the fall semester because of secondary violations that occurred last season under then-coach Ralph Friedgen, the school announced Saturday morning.

The violations involved the “countable athletically-related hours” that players had during the 2010 fall semester. The athletic department found that an extra 1.25 hours per week were used last season over the permissible 20 hours per week. The release also said “some administrative interns involved with football also were in attendance during non-mandatory summer workouts prior to last season.”

Maryland self-reported the violations to the NCAA and the ACC and recommended imposing penalties that will be imposed during this season. The football team will be limited to 17.5 hours of athletically related activities per week during the semester. The penalty will be imposed only during weeks when fall classes are in session.

The football administrative interns will be restricted from observing and participating in on-field activities during the preseason practice period in August. The graduate assistants will be prohibited from participating in the first 16 practices in August.

Rules-education sessions regarding playing and practice-season regulations, as well as rules involving permissible and non-permissible summer activities, will be conducted with all football players, coaches and football-related staff.

Letters of admonishment will be sent to the two Friedgen assistants who were retained by new coach Randy Edsall — offensive line coach Tom Brattan and wide receivers coach Lee Hull — and all non-coaching staff members still employed.

“We have already put processes and controls in place to better ensure things like this don’t happen in the future,” Athletic Director Kevin Anderson said in a statement. “It’s fundamental to me and to the department that we operate with integrity and do things the right way as we move forward. Our view is that we need to deal with the past so we can be better tomorrow.”

The athletic department learned Friday that the NCAA accepted those penalties as sufficient.

“We’re disappointed that this happened,” Edsall said in the release. “It’s important to me that we always abide by the rules and regulations set forth by the NCAA. We have put a plan in place to deal with this situation, and I am glad we can now begin to put this behind us. We are looking forward to August 9, when we get on the field for the first day of preseason practice.”
