The Bulldogs senior, who leads the team in scoring, had to be taken off the court on a stretcher last weekend, and the initial diagnosis was a broken clavicle that would have ended his only season under Brad Stevens.
However, both Clarke and his father, Conley, told CBSSports.com that Clarke will miss Wednesday's game at La Salle and is expected to be cleared to play against the Owls next Saturday.
"The doctors said I needed to be symptom-free for a week," Clarke said, "and I didn't have any symptoms for the first time on Thursday."
Clarke is averaging 16.3 points per game and shooting 44 percent from beyond the arc this season. He suffered the injury when he crashed into the base support of the backboard against Dayton. He wound up suffering a sprained neck.
The Bulldogs are 2-0 since Clarke suffered the injury, including a victory over No. 8 Gonzaga on Saturday night in Hinkle.
