On the next play, Squirek intercepted Joe Theismann's screen pass and returned it for a touchdown to give the Raiders a 21–3 halftime lead.
Squirek's most famous play is his interception in Super Bowl XVIII against the Washington Redskins: before the end of the first half, a Raiders drive stalled when Jim Plunkett's third down pass was incomplete, but Ray Guy's 27-yard punt pinned Washington at their own 12-yard line with 12 seconds left in the half.
