Yahoo Sports reports: The Texas Rangers have placed shortstop Corey Seager on the seven-day concussion list, clearing the way for second baseman Josh Smith to return from a six-week absence that included a bout with viral meningitis. Smith was available off the bench Monday night at home against Minnesota. The 28-year-old was primarily the second baseman before being sidelined by glute and wrist injuries in early May, but he can play all four infield positions and has been an outfielder as well for a team that's currently dealing with several injuries.
