Colorado quarterback Jordan Webb and former CU offensive lineman Alex Lewis were booked Saturday on charges of second-degree assault from an incident at 3:06 a.m., according to a Boulder County Sheriff's report.
Lewis, the starting left guard who announced Friday he was transferring to Nebraska, was also charged with two counts of harassment.
"Jordan's exact involvement in this incident is still being investigated," first-year CU coach Mike MacIntyre said in a statement.
"We continually stress the importance of appropriate behavior to our players and do not tolerate any detrimental conduct in our football program. Once all of the facts come to light, if Jordan is found responsible for any misconduct, he will be disciplined according to team rules.
"As for Alex Lewis, as of Friday he was off of the team when he did a media interview and announced that he is transferring to Nebraska. Since he is no longer a Colorado Buffalo, it will be up to Nebraska to decide what discipline he might face."
Lewis' attorney, Donald Brenner, said on his way to Boulder on Sunday that he doesn't know any details.
"From my preliminary investigation, my client got involved in a bad situation," Brenner said. "Justice will play itself out."
Webb, who started most of last year's 1-11 campaign, had surgery to repair a torn anterior cruciate ligament in his knee this past spring and hoped to return by late September.
Lewis and Webb were not available for comment.
Second-degree assault in Colorado is a felony and considered a violent crime — it carries a mandatory prison sentence if convicted.
