Coach Kyle Shanahan said Monday that Kittle has a sore calf and will be day-to-day, Cam Inman of The San Jose Mercury News reports.
Kittle logged all 70 offensive snaps during Sunday's 30-28 loss to the Packers en route to team highs in catches (seven) and receiving yards (92) on nine targets. He almost doubled up his stat line (8-95-0) on the season prior to Week 3 in the process, but he also emerged from the contest with a health concern. Considering Shanahan's comments, Kittle likely will be limited in practice when the 49ers post their first injury report of the week Wednesday, after which his status bears watching for next Sunday's divisional showdown with the Seahawks.
