Montgomery (ankle) was present for Wednesday's practice, Tom E. Curran of NBC Sports Boston reports.
Curran notes that Montgomery, who was carted off the field during the Patriots' preseason finale, looked "spry" Wednesday. The Patriots will release their first Week 1 injury report later in the day, when it will be revealed whether Montgomery is listed as a full participant. In any case, the change-of-pace back's presence at practice to begin the week bodes well for his chances of suiting up Sunday against the Dolphins.
