Each week, CSNChicago.com takes a look at the injury report from both the Cubs and White Sox, presented by Service King.
Austin Jackson underwent successful left knee surgery on Wednesday to repair a torn meniscus he suffered on June 9. The White Sox outfielder will be on crutches for two weeks and reexamined in four. He is currently on the 15-day disabled list.
Jake Petricka (torn labrum in right hip) and Daniel Webb (Tommy John) had successful surgeries on June 10. Both pitchers are expected to miss the remainder of the 2016 season.
The Cubs enjoyed a week without much in the way of injuries. Tommy La Stella was added to the disabled list last week as Chris Coghlan was re-acquired. La Stella won't be eligible to return to the Cubs for another week.
Jason Hammel has gotten past his leg cramping issue from Memorial Day and picked up where he left off before that start against the Dodgers at Wrigley Field.
But the main injury news came in the form of Willson Contreras' promotion to the big leagues. With 39-year-old David Ross in the final year of his playing career and Miguel Montero only about a month removed from a back injury, the Cubs have some insurance at the most physically demanding position on the diamond. Contreras figures to only catch here or there, but if Ross or Montero get banged up, the 24-year-old catcher could slide in for a larger role.
Jorge Soler is still rehabbing his hamstring injury and, though he's due to come off the disabled list next week, he probably won't be back right after the 15 days are up.
Cubs president of baseball operations Theo Epstein met with the media Friday at Wrigley Field and reinforced that Kyle Schwarber has no plans on playing in 2016, though his rehab is going well.
