Lewis, a Delaware transfer who sat out last season, suffered the injury about two weeks ago, a source told CBSSports.com. The Explorers won't know the timetable for his return until the first week of November.
“We're going to get it X-rayed on November 5,” head coach John Giannini told City of Basketball Love. “If it's healed, then he comes back to practice. If not, it's a week-to-week thing.”
Lewis, a 6-foot-3 combo guard from Trenton, N.J., averaged 5.2 points and 2.6 assists during his one season at Delaware. He is expected to be one of the key backups for Giannini's Explorers this season, providing terrific perimeter defense.
