Kittle (calf) is running at Friday's practice, but he doesn't have a helmet and doesn't appear to be doing the usual routine, David Lombardi of The Athletic reports.
Kittle started warming up with his teammates but then did some running on his own off to the side while healthy players went through stretches. After missing practice Wednesday and Thursday, he'll almost certainly have a game designation when the Niners release their final injury report Friday afternoon. They have a 4:05 p.m. ET kickoff for Sunday's home game against Seattle.
