Mike Veisor was a third round selection (45th overall) of the Chicago Black Hawks in the 1972 NHL Draft. He spent his first pro season with the Dallas Black Hawks of the Central Hockey League in 1972-73. He successfully made Chicago's roster the following season as a backup to workhorse Tony Esposito. Veisor played in 10 games in his rookie season, posting a 2.23 goals against average with a shutout. Veisor split the following year between Dallas and Chicago, appearing in 9 games for the NHL club with a 4.70 GAA.

In 1977-78, Veisor once again became his Esposito's primary backup with Villemure's departure. He would see action in 40 games over the three seasons from 1977-78 to 1979-80 with the Black Hawks.
