49ers fullback Kyle Juszczyk is expected to be sidelined for most of the remainder of training camp with a hamstring strain.
Meanwhile, the 49ers took preventive measures on Wednesday with tight end George Kittle. When Kittle began feeling tightness in his hamstring, the club pulled him out of practice for the final 30 minutes to work on a side field with the strength and conditioning staff.
“(Kittle) checked out all right, but we took him out of there before something bad happened,” coach Kyle Shanahan said Thursday after the 49ers held a walk-through rather than their scheduled fully-padded practice in Santa Clara.
