Rockies shortstop Troy Tulowitzki and outfielder Carlos Gonzalez, who had season-ending surgeries last August, could play Monday against the Reds at Salt River Fields at Talking Stick. Weiss said the decision would be made after Tulowitzki, who had left hip labrum surgery, and Gonzalez, who had a left knee procedure, went through a workout on Sunday. If they play, it would be a week or so earlier than expected.
