Jamey Eisenberg on Quentin Johnston

Chargers injury updates: WR Tre' Harris (hamstring) is week to week, Harbaugh said. Would be another notable loss for that room. It is "possible" WR Ladd McConkey (foot) works back into practices this week, Harbaugh added. WR Quentin Johnston (chest) expected to be limited again this week. No firm timetables given on RT Joe Alt (neck) and S Derwin James (hamstring). LB Bud Dupree (neck) day to day. CB Donte Jackson (hamstring) still week to week. [Retweeted](
