BOULDER — Colorado football coach Mike MacIntyre said Friday that signee Sam Kronshage told him his recent tweet that included a racial slur was sent by a schoolmate using his cellphone.

MacIntyre said he will continue investigating the situation after Thursday reports that the offensive lineman from The Woodlands (Texas) High sent a tweet to a black baseball player from a rival high school.

The tweet, according to a Dallas Morning News report, contained the N-word and ended with "#SEASONOVER." It has since been removed from his Twitter account.

MacIntyre, in his first year at CU, said he talked to Kronshage and his parents that night. Sam told him he was swimming at a graduation party Saturday, while The Woodlands was defeating the rival player's school in a playoff game next door, and saw the tweet on his cellphone when he got out of the pool.

"He was very calm," Mac- Intyre said. "That's why I believe he was 100 percent telling the truth."

Kronshage's father sent MacIntyre an e-mail detailing his son's work with Well Aware, a nonprofit organization that provides clean water for East Africa. His mother told MacIntyre that her sister is married to a Nigerian.

Kronshage chose CU over Duke, Louisiana Tech, Southern Methodist and Texas State. He committed to CU under previous coach Jon Embree and was recruited by Kanavis McGhee; both men are black.

"I do believe them," Mac- Intyre said. "So we're in the process of trying to make sure what we've been told is definitely real."

The coach said he is considering banning his players from having Twitter accounts.

MacIntyre said CU's Office of Student Conduct will get involved and it will investigate if it's determined Kronshage's actions violated CU's code of conduct. MacIntyre said he will go along with whatever decision the school makes.

He said if Kronshage did send the text, "there would definitely be some strict, strict discipline take place," including losing his scholarship.

"I told him, 'If you lied to me, you're toast,' " he said.

MacIntyre said he hopes to resolve the situation shortly.

"It's tough," MacIntyre said. "I believe the truth always comes out. I may be naive, but I think the truth always comes out. I also (believe in the) honesty of the family and the character of the kid."

In other CU news, redshirt freshman tailback Davien Payne, who wasn't listed on the spring depth chart, was declared academically ineligible. Also, four team captains will be announced June 19.
