According to a police report obtained by the Boulder Daily Camera, witnesses told police that Lewis shoved the alleged victim head-first into a wall before both Webb and Lewis forced him to the ground and punched him. Lewis then threw the victim into a parking kiosk, witnesses said, knocking him unconscious.
Both Webb and Lewis appeared in court on Monday after being released on $10,000 bond. Attorneys for both players said their clients were innocent of the charges, which include two counts of harassment for Lewis in addition to the assault charge.
Buffs first-year head coach Mike MacIntyre said in a statement on Sunday that Webb "will be disciplined according to team rules" if "found responsible." He said any team discipline for Lewis would be handled by Nebraska, the school to which Lewis decided he would transfer just last week.
Per the police report, Lewis told police he and Webb had been in Denver celebrating a friend's graduation before taking a taxi back to Boulder. They bumped into the alleged victim on their walk home, leading to an argument. Lewis said the victim threw a punch at him, which missed, after which Lewis pushed the victim away. Lewis said he then avoided another punch and pushed the victim again. Lewis said Webb was never involved in the shoving.
Lewis also, however, told police that he had a grand total of 22 drinks during the evening: "6 glasses of wine, 10 beers and 6 shots of various other alcohol."
Prosecutors are expected to formally charge Lewis and Webb during a hearing on Wednesday.
Webb appeared in 10 games for Colorado in 2012 as the team's primary starter, throwing for 1,434 yards with eight touchdowns and eight interceptions. Webb was expected to claim the starter's job again in 2013 before a torn ACL suffered during spring practice likely ruled him out for the season. A fifth-year senior, Webb will need an injury waiver from the NCAA for a sixth year of eligibility to continue his career with the Buffs.
