Braun was scheduled to take some swings to test his injured right hand prior to the Brewers' game against the Washington Nationals on Tuesday. He hasn't played since June 9 and landed on the disabled list five days later with a nerve injury between his right thumb and index finger.
Roenicke doubts Braun is healthy enough to accomplish the tasks that would be required of him to be back on the field in the next couple of weeks.
"Unless things change in a hurry, where he swings and the next day there's no pain, and he swings again and now we can accelerate that. But it doesn't look like it's going to be that way."
The Brewers have lost six straight games and are 7-12 overall since their star outfielder was sidelined. Heading into their game on Tuesday, the Brewers were 32-49 overall.
Braun was hitting .304/.380/.509 with nine home runs and 36 runs batted in at the time of the injury.
