Willie Nelson has canceled two more weekend concerts because of illness, according to Rolling Stone.

Publicist Elaine Schock gave no details on Nelson’s sickness, but she told The Associated Press he plans to be back on the road again for a Feb. 16 concert at a San Antonio rodeo.

CHICAGO – JULY 11: Singer Willie Nelson announces plans for an event marking the 20th anniversary of Farm Aid during a news conference July 11, 2005 in Chicago, Illinois.

Nelson founded Farm Aid in 1985 as a day-long music festival in Champaign, Illinois, with proceeds to benefit struggling family farmers.

It’s the second time in recent weeks the 83-year-old country legend has missed shows because of sickness – he canceled two of his five shows in Las Vegas in late January because of a bad cold.

Nelson played to a packed house at a November concert at the Stafford Centre in Sugar Land.

Nelson is up for a Grammy Sunday for Best Traditional Pop Vocal album for his tribute to the Gershwin brothers.
