LSU coach Les Miles says freshman running back Derrius Guice will need additional tests after reportedly losing consciousness Wednesday at the team's practice facility.
"Everything I hear is he's OK," Miles said at SEC media days in Hoover, Alabama. "They just have to do tests to make sure.
"I don't know if it's fatigue. I don't know if it's blood work. I don't know if it's low blood pressure. I don't have any idea. I can only tell you tell that it was a concern that we needed to back him off and get him relaxed, so we did."
A source told ESPN that Guice remains hospitalized. A source earlier had said that the running back had left the hospital.
Guice lost consciousness Wednesday, according to a report in the Baton Rouge Advocate. The newspaper, citing two sources, reported that Guice had felt sick earlier Wednesday and then traveled to LSU's practice facility. He was not working out when he lost consciousness.
An LSU spokesman confirmed that a player was hospitalized Wednesday but did not reveal his identity or for what.
Guice was the eighth-ranked running back and No. 96 overall in the ESPN 300 for the class of 2015.
A native of Baton Rouge, Louisiana, he was named MVP of the U.S. Army All-American Bowl after racking up a record 153 receiving yards and two touchdowns on just two receptions.
