SANTA CLARA, Calif. – Before being pulled off Levi’s Stadium’s loose grass field less than an hour after practice began by coach Jim Harbaugh, the San Francisco 49ers did go through the paces for a bit in front of a couple thousand fans.

A few highlights, then, of the 49ers' final public practice.

• Wide receiver Michael Crabtree was still not in attendance, as he was in Texas the day before for the birth of his son Michael III.

• Even before the public practice was cut short, the poor condition of the field was obvious, from divots flying out when players made cuts to the discolored spots in the middle of the field. And if Bruce Ellington tweaking his right ankle in a one-on-one drill with cornerback Chris Culliver was not proof enough, then Stevie Johnson taking a spill untouched on an out pattern at the goal line and jerking his left leg sealed it.

• Phil Dawson, one of the more accurate kickers in NFL history, continued to work on his craft after missing a pair of field goals in Sunday’s 34-0 exhibition loss to the Denver Broncos by kicking numerous field goals. If Andy Lee was not holding, then Dawson had a metal holder in his place so he could work solo.

• Ellington, LaMichael James and veteran Anquan Boldin were the three players fielding punts.

• Cornerback Tramaine Brock picked off McLeod Bethel-Thompson on a pass intended for David Reed on the right sideline and returned it 25 yards for a touchdown.
