Hyde has been suspended from all football team activities after a weekend arrest, while Roby will not travel to Chicago to be part of the Big Ten Media Days this week and could face further discipline after being arrested this weekend in Indiana.
Baugh has been given a one-game suspension and lost his summer financial aid, while Gardner will sit out the 2013 season and was sent home to Indiana.
"I have a clear set of core values in place that members of this football program are constantly reminded of and are expected to honor," Meyer said. "There are also expectations with regard to behavior. I expect our players to conduct themselves responsibly and appropriately and they will be held accountable for their actions."
"Swift, effective and fair discipline is the standard for our entire athletics program," director of athletics Gene Smith said. "I applaud Coach Meyer for his immediate actions."
Hyde has been suspended from all football team activities pending the outcome of the student code of conduct and criminal investigations. Per multiple reports, Hyde is a person of interest in a Columbus police report regarding an assault on a woman that took place over the weekend in Columbus.
Before the charges, Hyde was slated to start in the OSU backfield and was projected by many to be a potential star. Meyer called him "as good as there is in the country" during spring, and he is on the watch list for the Doak Walker Award, which goes to the best running back in the country, and the Maxwell Award, which goes to the best player in the nation. He has been expected by many to challenge to become the first 1,000-yard running back under Meyer.
Hyde ran the ball 185 times for 970 yards and 16 touchdowns in just 10 games in 2012 thanks to an early-season sprained MCL. In all, he averaged 107.6 yards per Big Ten game and had 14 touchdowns in eight league contests on the way to second-team all-conference honors.
In his career, he has rushed 315 times for 1,677 yards and 22 touchdowns while also catching one TD pass.
Roby is a Thorpe Award candidate after leading the nation last year in passes defended per game on the way to All-America status.
He was expected to be a spokesman and leader for this year's team despite his junior status, but he will not go to Chicago to represent the squad this week at the media event that begins Wednesday. He could face further discipline after being arrested on a Class-A misdemeanor charge of assault this weekend in Bloomington, Ind.
Per a statement from Bloomington police, "On July 21, 2013, at approximately 2:40 a.m., Bloomington Police were dispatched to the Dunkirk Bar, located at 430 E. Kirkwood Avenue, regarding a disturbance. When officers arrived they located Bradley James Roby being detained by private security officers hired by the bar. Bar staff, security officers, and an independent witness reported that Mr. Roby had been inside the Dunkirk Bar and had attempted to start a fight with another pattern. He was removed from the bar by bar staff. He then attempted to re-enter the bar to locate his friends. At that point he was stopped by security officers and told he could not re-enter the bar. Mr. Roby then struck one of the security guards in the chest, causing a complaint of pain. He was then wrestled to the ground and detained until police arrived on the scene."
His charges are punishable by jail time and a fine. Roby was released on bond and faced a hearing this afternoon.
Baugh has been removed from all team activities and will sit out the first game of the season, Aug. 31 vs. Buffalo, for his arrest last weekend for underage possession of alcohol and possessing a fake identification. His actions will also result in the loss of his summer aid.
He is a true freshman tight end from Riverside, Calif., who was named a four-star recruit by Scout.
Gardner is a three-star offensive guard who has been sent home and will not be a part of the 2013 team after he was charged Saturday night by Columbus police with obstruction of official business.
