News: Johnson (hand) will begin a rehab assignment with Triple-A Gwinnett on Monday.
Impact: Johnson hasn't seen live game action since suffering a fractured left hand April 30, but is scheduled to play three rehab games before joining the Braves in San Francisco on Thursday. He took batting practice at Turner Field on Sunday after playing in extended spring games over the weekend, and doesn't appear to be experiencing any lingering effects. Upon his return, Johnson could cut into the playing time of Alberto Callaspo at third base.
News: Callaspo is not in the lineup Sunday against the Brewers, David O'Brien of the Atlanta Journal Constitution reports.
Impact: He's started four straight games at the hot corner but will give way to Pedro Ciriaco on Sunday afternoon. Callaspo is hitting just .137 in May, but with the team shallow at the position, he should continue to see relatively consistent playing time for the foreseeable future.
