Hernandez did not travel with the team to London, but many suspected that he could fly to England later in the week. ESPN Boston's Mike Reiss reported that Hernandez "was expecting to be a new dad," and that was possibly what held him up.
Rather, Schefter reports that Hernandez's ankle was not responding to treatment, and that the tight end was struggling to cut. He will also have next week to recover, as the Patriots have their bye week.
So far this season, Hernandez has only 17 receptions for 143 yards and two touchdowns. He injured his right ankle in a Week 2 loss to the Arizona Cardinals, and missed games in Weeks 3-5.
