CINCINNATI -- The Cubs placed outfielders Ryan Sweeney and Justin Ruggiano on the disabled list, and the team was still testing the two players to determine if either injury is season ending.
Sweeney was placed on the 15-day disabled list with a left hamstring strain on Wednesday. Ruggiano was put on the 15-day DL, retroactive to Saturday, because of left ankle inflammation.
Manager Rick Renteria said both players were undergoing tests to determine the extent of their injuries.
The Cubs recalled Logan Watkins and Jorge Soler from Triple-A Iowa to take their spots on the roster.
Sweeney, who was batting .251, had to leave Tuesday's game after one at-bat because of the injury. He said he injured it running to first base in the second inning. Sweeney missed time in June because of a right hamstring strain.
Ruggiano was batting .323 in his last 44 games with nine doubles, four homers and 20 RBIs. He said his ankle has been bothering him for the last two weeks, and he has not started a game since last Thursday.
