Double-A Rocket City placed Klassen (concussion) on its 7-day injured list Tuesday.
ANALYSIS
Klassen was hospitalized after being struck in the head by a line drive in his May 11 start versus Montgomery, but he's since been discharged and is said to be improving after being diagnosed with a concussion. It's not yet clear when the 23-year-old will be ready to pitch in games again.
