Phoenix — Tom Glavine's return is a go.

The left-hander pitched five solid innings in an injury-rehab start for Class AA Mississippi on Saturday and is scheduled to start for the Braves on Thursday against Chicago.

Glavine, 42, was charged with four hits, three runs (two earned) and one walk with one strikeout in the game against Jacksonville, and retired the last six batters he faced.

His return will come against the last team he faced, the Cubs. Glavine lasted three innings in a June 10 start at Wrigley Field and left with elbow soreness after allowing six hits, four runs and four walks.

He was diagnosed with a partially torn flexor tendon, and doctors didn't know if the injury would require surgery. After a long period without progress, his condition improved rapidly in recent weeks.
