The victim, a Temple student, reported the alleged assault on Thursday to Temple Police who turned the case over to Philadelphia detectives.
Police said that she showed signs of scratching, bruising and a bump on her head and complained of dizziness and blurred vision.
The victim told police that Johnson "had been abusive to her during their three year relationship," police said.
The incident occurred in a building called The Edge where the university rents several floors. Raymond Betzner, Temple spokesman could not say whether the incident occurred in university housing.
The 6-foot-4, 295-pound student from Willingboro. N.J. started in the first two games. Johnson was not at Saturday's game 37-28 win against South Florida.
He started at defensive tackle in the season's first two games against Villanova and Maryland and has seven tackles on the season. He was a team captain at Willingboro, where he played defensive end and tight end.
He's majoring in broadcasting, telecommunications and mass media.
Temple coach Steve Addazio refused to comment on Johnson's arrest or his status with the team.
"No comment. No comment," Addazio said after the Owls defeated South Florida, 37-28, in Saturday's Big East Conference game at Lincoln Financial Field. "You know what, this a great moment today. I'm going to really enjoy the moment, and really enjoy the players that are in that locker room right now. That's about where I'm at."
Betzner said it would be up to the coach to decide on whether Johnson would be suspended from the team. If found guilty, he could face university discipline which could include expulsion and losing his football scholarship. Johnson was a redshirt junior which means he sat out a year to get an extra year of eligibility.
