Answer based on context:

Coming off their win over the Redskins, the Dolphins stayed at home for a Week 11 AFC East showdown with the Buffalo Bills.  Miami trailed early in the first quarter as Bills kicker Dave Rayner made a 30-yard field goal, yet the Dolphins immediately answered with quarterback Matt Moore finding tight end Anthony Fasano on a 1-yard touchdown pass, followed by a 5-yard touchdown run from running back Reggie Bush.  Miami would add onto their lead in the second quarter with Moore connecting with fullback Charles Clay on a 12-yard touchdown pass, followed by wide receiver Davone Bess on a 4-yard touchdown pass.  Buffalo would close out the half with Rayner booting a 56-yard field goal. The Dolphins continued their dominating day in the third quarter with running back Lex Hilliard recovering a blocked punt in the endzone for a touchdown (the team's first TD off of a blocked punt since 1990).  The Bills tried to rally as linebacker Kelvin Sheppard tackled rookie running back Daniel Thomas in the endzone for a safety, but Miami's lead proved to be too much to overcome. This game also marked the first time since 1990 that Miami allowed 10 points or fewer in three-straight games.They have now become the 3rd team in NFL History to win 3 straight after starting season at least 0-7 ('78 Cardinals & '86 Colts).

Which player scored a safety?
Kelvin Sheppard
