Country music singer Randy Travis remains in critical condition after suffering a stroke during surgery.

The 54-year-old is in a Texas hospital. He was being treated for congestive heart failure because of a viral illness.

The viral illness led to a weakened heart muscle that eventually worsened into heart failure.

A cardiologist from the Tennessee Valley weighed in on Travis' condition, and the recovery ahead.

"It sounds like they had to operate to relieve some of the pressure on his brain, which may have indicated that it was more of a head bleed type of situation. I can't really speculate to that, but I think he's in for a long road. I think he's going to have to have some rehab and let's just assume his heart will get better," said Dr. Robert Huang, Erlanger Interventional Cardiologist.

Doctors said earlier Wednesday that Travis was in good health until three weeks before he was hospitalized, when he contracted a viral upper respiratory infection.
