Patton (concussion) didn't practice Wednesday, CSN Bay Area reports.

Before he was ruled out of Sunday's loss at Miami, Patton picked up 26 snaps but saw only one target, which he snared for 12 yards. Outside of a 102-yard performance in Week 9, he's surpassed 50 yards three other times, while failing to reach 30 yards in the other seven outings. With more misses than hits and no touchdowns to his name, his residence in the concussion protocol shouldn't hold much sway over the 49ers' offensive prospects. Nonetheless, he participated in aerobic exercises and weightlifting Wednesday, so he appears to be making some progress.
