Country legend Merle Haggard has cancelled his shows in February due to health issues caused by pneumonia in both lungs.

A statement released by his publicist said the singer-songwriter was still feeling weak from his recent struggle with the illness, for which he was hospitalized in December, and has decided to seek further treatment.

The statement said Haggard "is hopeful he will be back on the road later in the spring."

Haggard had shows scheduled in California and Nevada in February.

The 78-year-old singer of hits like Okie From MuskogeeMama Tried and Workin' Man Blues had a battle with lung cancer in 2008.

The rough and tumble Haggard, who had several brushes with the law before becoming a country star, is known for his innovative songwriting and working man's point of view. He continues to keep up an ambitious touring schedule.
