Garland suffered the injury early in the Commodores' game against Kent State on Friday.
A 6-foot-2 native of Nashville, Tennessee, Garland was the No. 1 point guard in the 2018 high school class and is a projected lottery pick in the 2019 NBA draft. He is averaging 16.2 points, 3.8 rebounds and 2.6 assists per game while shooting 47.8 percent from 3-point range. He scored 33 points Monday during a win over Liberty.
"He's going to get some further testing tonight. Hopefully we get some good news in the next 48 hours," Vanderbilt coach Bryce Drew said after Friday's game. "We will obviously be careful with his injury. He obviously has a bright future in basketball, and we just want to make sure we give him the best care we can for him to figure out what's the plan of attack."
Without Garland, Vanderbilt suffered its first loss of the season, 77-75 to Kent State. Sophomore Maxwell Evans saw an increased role in Garland's absence, playing 21 minutes and finishing with 8 points and 4 rebounds.
