Tyler said Tuesday after a players' only throwing session at Howard Jones Field that he could be suspended or expelled from school by the Office of Student Judicial Affairs for allegedly spitting on a female student and groping another female student in April.
"The worst (case scenario) is them kicking me out of school," Tyler said.
Gary Klein of the Los Angeles Times first reported the allegations against Tyler.
The allegations come at a time where Tyler, Scout's No. 2 running back recruit in the Class of 2007, seemed to be putting everything together.
Playing sparingly in his first two seasons because of injury, Tyler was the Trojans' leading rusher last season with 913 yards and nine touchdowns as a redshirt junior and is listed alongside Dillon Baxter, Curtis McNeal and D.J. Morgan as the No. 1 running back on the post-spring depth chart.
More importantly, he only needs to pass two more classes to receive his degree in sociology.
"I'm disappointed," Tyler said. "I've never really been in trouble before. I'm disappointed for my family and my teammates. I'm one of the oldest people on the team and to be getting in trouble…"
Tyler said athletic director Pat Haden and the coaching staff have been very supportive, even bringing him closer to head coach Lane Kiffin.
The two memorably clashed over Tyler's pulled hamstring, an injury he suffered on the first day of spring and attributed to a lack of organized stretching.
"I feel like I came closer to the coaches since this happened," Tyler said. "I meet with them a lot more. Me and Lane's relationship became a lot closer."
Tyler said he does not expect further punishment from the football program or athletic department, but would be willing to speak to the team about his ordeal.
"I need to be a leader," Tyler said. "I'm really not a talkative person, but they (the coaches) have been saying lead by example. I haven't been doing that either.
"You know, I'm just trying to turn everything around and start doing that."
