Michael John Bettiga (pronounced "Bet-TEE-ga") (born September 10, 1950) is a former American football wide receiver who played for the San Francisco 49ers during the 1974 NFL season.

A multi-sport star, Bettiga was named to All-Golden Valley Conference teams for basketball and football at the junior college level and later set a series of school records at Humboldt State University running the 120-yard high hurdles.

[10] During the 1970 season, Bettiga also began to make his mark on the football field as a "number one" wide receiver for College of the Redwoods.

[11] His combination of size, speed, and leaping ability made him a potent scoring threat, and he was named by coaches to the 1970 All-Golden Valley Conference first team in December of that year.

[19] He also continued to make a splash with the football team, whose offense was touted as an "aerial circus" during his 1972 senior season.

At split end, Bettiga was the favorite target of Lumberjacks quarterback Gary Peterson and both he as a receiver and the team as a whole were number two in the Far Western Conference by mid-October.

[25][26] He was one of 34 draftees and undrafted free agents invited to the 1973 49ers training camp at University of California at Santa Barbara.

[28] He managed to make it back, however, and was the surprise starter at flanker announced by head coach Dick Nolan for an early August pre-season game against the Cleveland Browns.

He was inactive for almost the entire season and never saw game action, stockpiled by the team as a member of the practice squad.

[32] He signed a $30,000 contract with the 49ers for the 1975 season,[33] but was knocked out of action by another shoulder injury in an August 10 preseason game against the Cleveland Browns.

[19] He graduated from Humboldt State in 1975 with a bachelor's degree in physical education with a minor in history, and moved the same year to Fortuna High School, where he coached track, football, basketball, and tennis.
