Three whole games.
Byrd, a rookie who could very well be the Bills' MVP this year, became the NFL's sole interception leader when he came down with one of Matt Cassel's four interceptions in a 16-10 victory over the Kansas City Chiefs in Arrowhead Stadium.
One more and Byrd will tie Buffalo's franchise record set by Billy Atkins in 1961 and tied by Tom Janik in 1967.
Byrd's interception was a big one. It came at the Bills' 23-yard line to end a 13-play Chiefs possession that seemed destined for the end zone just before the two-minute warning.
Left cornerback Terrence McGee was responsible for Cassel's other interception.
