Rios' mother told the Miami Herald that her son was sick.
"First of all, Eddie was not suspended for being sick," Hurricanes coach Frank Haith said on Tuesday, according to the Herald. "Whether or not he's sick or not is not part of the reasoning for the suspension. But we have rules in place for all of our guys."
Haith said that the coaching staff had a difficult time reaching Rios or getting him to see a team doctor. According to the coach, "not communicating with your coaches and following protocol" likely spells the end of Rios' career at Miami.
"All of our players know that when you're sick and we ask you to do things, we're trying to help you," the coach said, according to the Herald. "This is Eddie's second suspension. So, we need to move forward. Eddie is a nice young man. I like Eddie. But we have to follow rules. We would like to move forward from there."
Rios was also suspended Dec. 2 and reinstated two days later. The latest suspension was for a lack of communication with coaches and violating team protocol, the Hurricanes said.
He's averaging 4.7 points and 12.3 minutes and has started four times this season.
The Hurricanes (12-3, 1-1 Atlantic Coast Conference) won their fifth game in a row Sunday at then-No. 24 Boston College and host Maryland on Wednesday.
