Atlanta Braves right field Jason Heyward left Thursday night's game against the Reds in the second inning with an injured right hamstring, the Atlanta Journal-Constitution reported.
Heyward was injured while sliding into third base, and the Braves reported that it was a strained hamstring.
Heyward will be re-evaluated on Friday.
Heyward was replaced by Reed Johnson.
Heyward is hitting just .225 with seven homers in 66 games this season.
