Navaira was driving his tour bus March 23 when it slammed into the freeway barrels, throwing him through the windshield. Doctors performed two brain surgeries and repaired an aneurysm on his right lung.
The 45-year-old singer is expected to have trouble with his memory and concentration as he recovers. But his doctors have said Navaira has been able to stand, eat, sign his name and talk with his family.
Navaira, known to his fans as Emilio, has released more than a dozen albums with his band. He won a Grammy for best Tejano album in 2003 with "Acuerdate."
