CINCINNATI -- Reds closer Aroldis Chapman threw 25 pitches during batting practice on Tuesday, passing the final test before he can begin a rehabilitation stint in the minors.

Chapman might pitch at Class A Dayton on Thursday, his first time in a game since suffering a head injury. He's hoping to be activated after four or five appearances in the minors.

The left-hander was hit on the forehead by a line drive during a spring training game in Arizona on March 19. He had a plate inserted above his left eye and nose to help fractures heal. Chapman was one of eight Reds who opened the season on the disabled list, most in the majors.

Jonathan Broxton is closing games in his absence.
