The University of Missouri's men and women's swimming and diving coach is on administrative leave while allegations of team management issues are investigated.
The athletic department announced the action involving Greg Rhodenbaugh on Monday but did not provide more information about the allegations.
Athletic director Jim Sterk said in a news release that student-athletes recently made officials aware of serious team management problems in the men's and women's programs.
Associate head coach Andrew Grevers will be interim coach during the investigation.
Rhodenbaugh is in his ninth year as coach at Missouri after coming from Arizona. The Tigers' men and women teams finished eighth- and 11th at the 2016 NCAA Championships, both program highs. The school also had its first individual national champion, Fabian Schwingenschlogl, in 2016.
