ANALYSIS: A few notable personnel changes, with the Patriots demoting rookie Nate Ebner on the punt protection unit after he was overpowered on the left wing in the Week 2 loss vs. the Cardinals. Linebacker Jerod Mayo joined the unit in place of Ebner, with veteran Tracy White moving to Ebner's spot on the wing. ... On the kickoff return unit, tight ends Daniel Fells and Michael Hoomanawanui played in the wedge, with Rob Gronkowski moved off that unit. ... Rookies Tavon Wilson and Brandon Bolden tied for the team lead with two special teams tackles apiece.
