Rob Gronkowski has been ruled out of the New England Patriots' Week 11 game at the San Francisco 49ers with a chest injury.

Gronkowski was not present for practice earlier Friday, marking the third straight day he was absent because of the injury sustained Sunday night in a loss to the Seattle Seahawks.

The team traveled to the Bay Area later Friday.

ESPN NFL Insider Adam Schefter has been told that the injury is "not overly serious" and that Gronkowski does not have a punctured lung, as has been reported.
