Yes it was SB 28, thanks for the correction.
From his Wiki page.
One of his most notable performances was in
Super Bowl XXVIII when
Thurman Thomas, after being tackled by
Leon Lett, fumbled the ball, Washington returned it for a 46-yard
touchdown to tie the game (13-13).
He also made a team-high 11 tackles, had an interception that eventually became an
Emmit Smith touchdown, forced a fumble to set up a field goal and knocked
wide receiver Andre Reed to the sidelines for a brief recovery time (sending a message to the Bills receivers). His performance was so dominating, that he received strong MVP consideration.

Dallas had a very sluggish first half, Washington was every where on defense hitting everything and keeping the Bills from breaking things open.
His TD return to start the 2nd half was scintillating, Cowboys were down at halftime 13-6, and set the tone for the entire second half. It was 20-13 to start the 4th and Buffalo started with the ball and it was a Washington pick that set the Cowboys up for the crushing 27-13 Emmitt TD run on 4th down from the 1.
Damn that was a good game and Washington was everywhere, seems to me that the announcers were constantly saying his name.
Never forget this guy when you're thinking of great Dallas history.
Big game James, man.
