[2] He entered the school in 1926 and made the varsity teams in four sports as a freshman: baseball, track and field, football, and basketball.

[4] He batted over .400 in baseball and was described as "an excellent running back in the single wing in football, and a kicker of no mean pretensions," as well as a "fine guard" in basketball, despite standing at 5 feet 9 inches (1.75 m).

"[4] As baseball and track were held at the same time, whenever Irvington played both sports at home, Weiner "did double duty.

"[15][16] Later, in a November game against Gettysburg, Weiner returned the opening kickoff 90 yards for a touchdown and was a major figure in Muhlenberg's 26–7 upset win, with The Morning Call noting of his kick return: "He went through the entire Gettysburg team in his wild dash ... shaking off one would-be-tackler after another, and seldom if ever has there been a finer exhibition of broken field running on the local gridiron.

"[22][23] That season, he kicked field goals that allowed Muhlenberg to defeat Penn State, 3–0, and Ursinus, 3–0, and played "sensational" in several others.

[25] He played his final game against Dickinson later that month and scored every point in a 7–0 victory, which allowed Muhlenberg to win the conference title with a record of 6–3.

[45] Weiner later said that in the entirety of his high school and college football career, he only missed one game due to injury, which was a broken shoulder.

[47][49] He also played for the local Jewish Community Center team that won the 1932 Pennsylvania championship and advanced to the national YMHA finals.

[51] He made the team and debuted in the Eagles' opener against the non-NFL Shenandoah Presidents on September 9, being a substitute for Ed Matesic and playing for a few minutes in the 8–7 win.

[54][56] Later, on September 30, he was a major part of the team's non-league 13–0 victory against the Reading Keys; the Reading Times praised him for having won against the Keys "almost single-handed," noting he "stole the show" from more well-known Eagles players such as Swede Hanson, running for a touchdown, throwing for a touchdown and kicking an extra point.

[59] On November 6, he played a part in the team's historic 64–0 victory over the Cincinnati Reds, in what remains the NFL's biggest regular season shutout ever.

[61] Weiner remained the last Eagles quarterback to throw two touchdown passes on four or less attempts until Tanner McKee did so against the Dallas Cowboys in 2024.

"[35] He concluded his tenure with the Eagles having appeared in five games, none as a starter, while he completed three of six pass attempts for 40 yards and two touchdowns, kicked three extra points and one field goal.

[35] A report following the signing noted that "Besides being a hard running back, he is quite adept in passing and punting and will give the Keys their most valuable triple threat man.

[73] Weiner signed with the Stapleton Buffaloes of the American Association (AA) for the 1936 season; his brother, Mickey, played for the team that year as well.

[75][76] He finished the season having appeared in six games, all as a starter, and was recorded to have converted one of two extra point attempts; other statistics are incomplete.

[83] In July 1934, a month after his graduation from Muhlenberg, Weiner began playing minor league baseball with the Stroudsburg Poconos.

[42] In January 1935, he was sent to the Huntington Red Birds of the Class C Middle Atlantic League, where he joined one of his college teammates, Horsey Heist.

[42] However, after being sent to Huntington, Weiner received a pay cut, with his salary only providing him $75 a month, and he began to complain to the team about it, which resulted in his release at the start of March 1935.

[90][91] He later recalled that his baseball career ended due to injury: "A guy sliding home wrecked my knee.

[94] During the 1935 football season, while he was still playing for the Reading Keys, Weiner became the head coach of a team known as the Lebanon Valley Exports, made up of several top local players.

[95][96] In 1936, Weiner was hired by Hillside High School in New Jersey as an assistant baseball and football coach and a teacher.

[99] Also that year, he led what he later described as his greatest baseball team, as they compiled a record of 21–1, had six players selected all-state, and won the GNT tournament.

[3][6] As head football coach, Weiner developed a team that won 23 consecutive games and a Group 3 title in 1942.

[2] He then had to leave his post in 1943 when he was drafted to serve in World War II, being a member of the United States Navy.

[3] He was hired as the coach of the sophomore football team at Parsippany Hills High School in 1967, and lost only one game in two seasons.

[3] Weiner was selected to the all-time all-star team of Muhlenberg College in 1952 and was later a charter member to the school's athletic hall of fame, inducted in 1979.
