Dealing with lower-body injury

San Francisco head coach Kyle Shanahan said Tuesday that Kittle is dealing with a "lower half" issue and isn't expected to participate during OTAs this week, Cam Inman of The San Jose Mercury News reports.

Shanahan added that the All-Pro tight end "could go," but the team is "being smart" with Kittle and there's a "good chance" he'll be held out until training camp. The tight end has dealt with numerous injuries over the last three seasons, so while his latest issue doesn't appear to be serious, the 49ers are expected to proceed with the utmost caution.
