Former Minnesota Vikings quarterback Joe Kapp made an appearance last Friday in Vancouver - and made it plain that old rivalries die very, very hard.

Kapp, 73, and former rival Angel Mosca, 74, had to be separated when Mosca didn't take kindly to flowers that Kapp offered him.

Aside from playing for the Vikes, Kapp was also a star in the Canadian Football League where Mosca also played in the sixties.

The two were sharing the stage Friday night during a CFL banquet.

The Canadian Broadcasting Company's web site reported that the confrontation "began after a highlight clip was shown from the 1963 Grey Cup, a game  where Mosca drilled Lions running back Willie Fleming in what many  considered a controversial late hit."
