College of Charleston president Glenn McConnell announced Wojcik's immediate dismissal after the school conducted two investigations last month. Assistant coach Antonio Reynolds Dean was named acting head coach.
McConnell offered no further comment or explanation for the firing.
"I want you to know, however, that the College of Charleston does not publicly discuss or comment on the specifics of personnel matters, unless there is a significantly compelling or legally mandated reason to do so," McConnell said in a statement.
There was no immediate comment from Wojcik or his representatives.
Wojcik came to Charleston two years ago after seven seasons at Tulsa. He compiled a 38-29 overall record at Charleston, including 14-18 last season.
The results of the first investigation -- that Wojcik verbally and physically abused players -- and a 50-page report of the allegations were made public in early July. The second investigation was conducted after a former Charleston player claimed he had a physical encounter with Wojcik in December 2012.
