SAN DIEGO -- Patriots defensive lineman Vince Wilfork wasn't sure the Patriots would get the call.
Wilfork, a member of the field-goal block unit, felt Chargers guard Louis Vasquez had committed a false-start penalty as Kris Brown lined up for a 45-yard field goal attempt to tie the game with 28 seconds remaining.
"In a situation like that, normally we don't move unless somebody else moves and it was 50-50," Wilfork recalled following the Patriots' 23-20 victory.
"He moved enough for us to jump across and the ref was on top of it. You just have to understand the situation. Five yards in a situation like that is a big five yards to try to tie the ballgame."
After the penalty, when Brown lined up for the 50-yard field goal, it clanked off the right upright.
"It played out how we wanted it to play out," Wilfork said. "We stayed onsides. They jumped. It moved them back five extra yards and it cost them the ballgame."
Linebacker Jerod Mayo is also a member of the field-goal block unit.
"About three of them just moved," he said of the key penalty, which came at the spot across from the Patriots' big linemen -- including Wilfork. "We'll take those five yards. It helped out huge for us."
