ESPN college basketball analyst Dick Vitale apologized Saturday for comparing Houston Texans running back Arian Foster to a prostitute.
In a three-minute clip previewing the upcoming documentary, Schooled: The Price of College Sports, Foster admits to taking money "on the side" while he starred at Tennessee.
"I don't know if this will throw us into an NCAA investigation -- my senior year, I was getting money on the side," Foster said. "I really didn't have any money. I had to either pay the rent or buy some food. I remember the feeling of like, 'Man, be careful.' But there's nothing wrong with it. And you're not going to convince me that there is something wrong with it."
Vitale responded to Foster's comments via Twitter on Friday, writing: "When they put their hand out like a prostitute & take it they don't say a word - moaning yrs later = SAD!"
Saturday, Vitale apologized for the remark via Twitter.
"I apologize if it offended u that I used prostitute 4 athletes taking cash. @marcisenberg made a gr8 point about NCAA rules @ term illegal."
Foster played at Tennessee from 2005-08.
The 90-minute documentary airs on EPIX on Oct. 16.
