Bomar fully recovered from his injury and played professional football as an end for the inaugural 1925 New York Giants of the National Football League (NFL) with Jim Thorpe, Century Milstead, and Owen Reynolds.
He was signed to the Giants by Harry March.

The first noteworthy game for Bomar was a 14–0 loss to the Frankford Yellow Jackets.
 After the Giants' poor first half, the Yellow Jackets led by 14 points.
During the second half the Giants recovered somewhat, with good passes from Jack McBride to Bomar but no chance of a comeback.
In a 13–0 victory over the Rochester Jeffersons, McBride threw a 27-yard touchdown pass to Bomar.
A 13–12 win over the Providence Steam Roller had a 24-yard touchdown pass from McBride to Bomar and an interesting ending.
The Giants were backed up near their end zone, faced with a fourth down and leading 13–10.
Providence was set for a blitz on the punter, but when he caught the ball he knelt in the end zone for a safety (not enough for Providence to win).
Against the Kansas City Cowboys, several passes from McBride to Bomar netted 24 yards in a 67-yard touchdown drive for a 9–3 victory.
Bomar had possibly his best day in a 23–0 victory over the Dayton Triangles before a crowd of 18,000.
Six of McBride's completed passes that day were to Bomar, including a 45-yarder for the Giants' first touchdown.
Bomar was selected to NFL president Joseph Carr's all-star team.

Although the Giants played well, the team experienced financial hardship during its first year.
Player salaries were so low that most had to take additional jobs to support themselves.
The team's brief practices, held at 4:30 p. m. each day to accommodate outside-work schedules, enabled little in-season improvement.
Overshadowed by baseball, boxing and college football, professional football was not a popular sport in 1925 and owner Tim Mara spent $25,000 of his own money during the season to keep the team going.
The financial struggle continued until the 11th game of the season, when the visiting Red Grange and the Chicago Bears drew more than 73,000 fans (a pro-football record) and an additional 20,000 were turned away.
This gave the Giants much-needed revenue, possibly altering the team's history.
In the 19–7 Bears victory, Grange intercepted a pass intended for Bomar and returned it for a touchdown.
