Lyles (back) will start for the Royals in Saturday's Cactus League game against the Cubs, Anne Rogers of MLB.com reports.
Lyles has been battling back spasms but got through a recent live batting practice session with no issues, clearing the way for his return to games. The veteran right-hander projects as the Royals' No. 5 starter but is being pushed by Alec Marsh and Daniel Lynch.
