Bayne spent a week at the Mayo Clinic undergoing treatment for what doctors have called an inflammatory condition. He was released last Thursday.
Roush Fenway president Steve Newmark says the team is encouraged by Bayne's progress but is being cautious in holding him out an additional week.
Newmark says Bayne should race in the All-Star race on May 21 at Charlotte Motor Speedway.
CLOSED AGAIN: North Wilkesboro (N.C.) Speedway is quiet again, with owners citing a lack of corporate support and the economic downtown for closing the track.
Speedway Associates Inc. announced the closing earlier this week. Speedway Associates obtained a lease-purchase agreement for the 5/8-mile track in 2009, 14 years after the last NASCAR races there. The track reopened last fall with six large and several smaller racing events.
QUICK ACTION: Kurt Busch 's profane tirade on the team's two-way radio at Richmond, Va., led to change.
Car owner Roger Penske apparently didn't admonish his driver for berating his team, particularly the engineering department and company technical director Tom German , during the race. Days later, the team reorganized.
"I feel like we've made great adjustments with what we're doing internally and that's to better understand how to build a better car," Busch said. "There's been great feedback and everybody's listening."
The team says German has been accepted into the Sloan School of Management at MIT, and will begin classes in June.
Penske officials say German expressed interest in the program last fall. The team says only 15 percent of applicants are accepted into the program.
