FAYETTEVILLE — San Diego State will be without the face of its baseball program when it plays a four-game series at Arkansas beginning Thursday night.

Aztecs coach Tony Gwynn will not travel with his team for a medical reason.

"I'm disappointed for him," Arkansas coach Dave Van Horn said Wednesday. "I talked to him two years ago about coming out here and he said he was looking forward to seeing the ballpark. I hope he's OK. I don't know all the details."

A San Diego State spokesperson said in an email Wednesday that Gwynn “remained in San Diego to take part in a clinical trial related to his ongoing health issues. This weekend was the only opportunity for him to do so.”

The Major League Baseball Hall of Famer, who is in his 11th season as San Diego State’s coach, has battled cancer of the salivary glands the past couple of years.

A story from the San Diego Union-Tribune earlier this week also said Gwynn underwent a medical test Monday. Gwynn called the test “routine.”
