"Anytime for me, because I've had shoulder issues, anytime something bothers you in your shoulder, you're thinking, 'What is it?' Because it could be anything," Parra said. "But I'm not worried about it."
Parra had his shoulder examined by doctors on Wednesday, and will be re-evaluated on Monday. Parra said he last played catch last Thursday, and each day meets with team trainers to learn the next step in his recovery.
He added that the extra rest he's had helped reduce swelling in his shoulder, which has relieved a pinching pain the impingement causes.
Parra last appeared in a game on July 24, allowing four earned runs over 1/3 of an inning on one hit and three walks against the Phillies. Prior to that rough outing, the 29-year-old left-hander had a 1.13 ERA over 11 appearances in July.
Roenicke said that if Parra's re-evaluation on Monday doesn't show much evidence of improvement, the Brewers would then consider making a roster move and sending Parra to the disabled list.
