Baylor women's basketball senior guards DiDi Richards and Moon Ursin were injured in a collision during practice Saturday, the school said.
Richards, one of the country's top defensive players, is out indefinitely with no specified time to return to basketball activities. Ursin is in concussion protocol.
The 6-foot-1 Richards suffered a spinal-cord injury without radiographic abnormality, which causes temporary impairment. Baylor said she was treated and released from the hospital, and is making progress from her injury.
Richards, of Cypress, Texas, won the 2020 Naismith and WBCA awards for national defensive player of the year, plus was named the Big 12's top defender. A starter as a sophomore and junior, Richards averaged 8.2 points, 4.9 rebounds and 5.7 assists, and had 52 steals last season.
The 5-6 Ursin, from Destrehan, Louisiana, has mostly come off the bench in her Baylor career, averaging 5.1 points, 3.0 rebounds and 1.4 assists last season.
Baylor, which went 28-2 overall and at 17-1 won the Big 12's regular-season title for the 10th season in a row, lost three starters to graduation -- forward Lauren Cox and guards Te'a Cooper and Juicy Landrum -- all of whom were drafted into the WNBA. With Richards out, only one full-time starter -- junior forward NaLyssa Smith -- is active for Baylor.
Baylor, No. 3 in ESPN.com's most recent rankings, is scheduled to begin this season Nov. 25 at home against Central Arkansas.
