EAST LANSING -- While Michigan State continues to wait on a charging decision in a sexual assault investigation involving three of its players, the program has added players to its list of those suspended.

On a conference call with reporters on Wednesday, Mark Dantonio confirmed that in the 11 days since Michigan State held its spring game, the team has had players placed on suspension who were previously active.

Dantonio used the program term "red lock," which he says is used for "various things," to describe the status of the players. Players moving in and out of "red lock" is typical, Dantonio said.

"There's constantly people in and out of different situations," Dantonio said.

Dantonio didn't mention any specific players while confirming that players have been placed under suspension since April 1. He also didn't not specify how many were suspended.

Michigan State held a total of 15 players out of its spring game. Ten of those players were on the field in team clothes, likely indicating injuries, and five were not seen on the field at all. Afterward, Dantonio declined to provide updates on any of them, outside of saying that running back LJ Scott is injured.

Michigan State has had three players suspended from team activities since earlier this year, after a sexual assault complaint was made against them on Jan. 17.

Michigan State continues to wait for a charging decision from the Ingham County Prosecutor, nearly three months after that complaint was filed. The Michigan State University Police concluded their investigation on March 14 and have submitted four warrant requests.

Michigan State held the last two of its 15 spring practices last week, and is now off from official practices until late summer.
