Petrino said there was not much new regarding Adams, who led the team in receiving before being sidelined last week. He believes Adams' condition has improved, but the 19-year-old's health remains a concern to the Razorbacks.
"He feels better," Petrino said. "He's got more tests to take. There's not a whole lot of information for me to give out on him because I don't know a whole lot. I'm not sure how long he'll be out. It will be up to the doctors.
"But the main thing is, he's doing good. He feels good. He has no headaches."
Petrino said after the Auburn game Adams may have suffered the stroke last Monday. If so, he practiced with the team Tuesday and went through a round of interviews with the media.
But Arkansas running back Dennis Johnson said the Razorbacks could tell there was something wrong with Adams last week.
"He was walking around moping," Johnson said. "He had his head down and his head was always hurting. Joe has never been like that. Joe is always active, making people laugh. He's a funny guy. I knew something was wrong with him when he was walking around like that."
Petrino said Adams was flown to Little Rock on Friday to visit with a specialist. He returned in time to watch Arkansas' 44-23 win from the sidelines with injured teammate Chris Gragg.
Petrino said Adams feels well enough to practice, but has not been cleared. Johnson said the receiver is talking and interacting with teammates more than he did last week, too.
When asked if Adams could play, Petrino said: "I wouldn't think he would play this week at all."
However, he said Adams is in good hands.
"There's a group of doctors that are working on it," Petrino said. "They're on top of it. They have a good group that's really working on it."
