PHOENIX - Diamondbacks ace Randy Johnson's scheduled rehabilitation start tonight for Triple-A Tucson has been canceled.
Manager Bob Brenly said Johnson was throwing well off the mound but was not comfortable fielding.
"All the reports have been good concerning his arm and knee," Brenly said. "We don't want to put him into a position where he is throwing well, his knee feels well and he comes off the mound to field a bunt and has something bad happen."
The five-time Cy Young Award winner had arthroscopic surgery two months ago.
Johnson reportedly was impressive in a 55-pitch outing Monday at a physical therapy and conditioning center in Phoenix. But physical therapist Brett Fisher told the Diamondbacks that Johnson looked tentative during fielding drills Tuesday.
The start was not rescheduled.
Meanwhile, right-hander Curt Schilling struck out six in four innings for Triple-A Tucson against Sacramento in his first rehabilitation start since breaking his right hand May 30.
Schilling, who allowed two runs on four hits and one walk, said he will make one more rehab start, then should be ready to rejoin Arizona's rotation.

ANKIEL SHARP: Left-hander Rick Ankiel allowed two hits in a seven-inning complete game for Double-A Tennessee, losing 2-1 to Carolina in a doubleheader opener.
