Cubs manager Joe Maddon confirmed that Ross was doing well after consulting with the training staff, and he expects his catcher to play on Saturday.
Ross exited after his at-bat in the eighth inning on Thursday. He said he felt a small, sharp twinge, and the area tightened up and released. Maddon ordered Ross to bunt to try to avoid further injury. Ross ended up striking out on a foul bunt.
"Joe was pretty adamant that I do not swing. 'Do not swing. Bunt. Drag bunt,'" Ross said. "I was like, 'All right.' We had the lead. I just wanted to try to get out of here with a win, worry about my body later."
Ross said he felt confident the tightness didn't involve his oblique. He once pulled an oblique while playing in Double-A, and this tightness felt different, he said.
Otherwise, the young Cubs are helping the 14-year Major League veteran feel young.
"If my body holds up, we'll be fine," Ross said. "These guys are great. It's a fun group to be part of. It's a group that asks a lot of questions. I've got to clean up my dance moves for after the game. I've got to get better at that."
