Kittle (calf) has been officially placed on IR by the 49ers.
As a result, Kittle will miss the 49ers' next three games, with Adam Schefter of ESPN noting that the team believes the tight end will be able to return to action when he's eligible to do so. That would put Kittle on track to rejoin the lineup Nov. 7 against the Cardinals. Until then, Ross Dwelley and Charlie Woerner are slated to head the 49ers' tight ends corps, with Tanner Hudson in the depth mix.
