The Marlins second baseman didn't sustain any further damage to his surgically repaired left thumb when he re-injured it last week.
Bonifacio went on the disabled list on Saturday, and the team is optimistic that he could be back as early as Aug. 19, the first day he is eligible to be reinstated.
The speedster initially injured the thumb on May 18 in Cleveland, where he suffered ligament damage. Surgery was performed on May 25, and two pins were inserted. The pins were not damaged by his latest injury, which occurred in the ninth inning of Game 2 of Friday's doubleheader in Washington.
Bonifacio basically tore some scar tissue when he made a diving attempt on Michael Morse's infield single.
The Marlins also are hopeful that Logan Morrison, on the DL since July 29 with inflammation in his right knee, will be able to return this season.
Morrison traveled to Vail, Co., to be examined by Dr. Richard Steadman. Morrison has a right patellar tendon injury.
The Marlins believe Morrison won't need surgery, and that with rest, he could return this season.
