Jerwa signed with the
Vancouver Lions in 1929, where he played alongside his brother Joe. Jerwa was traded to the
Boston Bruins in April 1931 and again played with his brother. His debut came against the
Montreal Maroons on November 14, 1931, but it wasn't until February 4, 1932, against the
New York Americans, where he scored a goal and made an assist, that he earned any points. He played 65 games with the Bruins but spent most of his time in Boston with the
Boston Cubs, with whom he played 101 games. He and
Joe Lamb hold the title for fastest two goals in the Eagles franchise at 14:50 and 14:53 on March 12, 1935. He played 16 games before the club was disbanded; he returned to the east coast in October 1935, this time for the
New Haven Eagles, a Bruins affiliate. After 45 games there, he briefly played for the Vancouver Lions, then went to the
Springfield Indians for 35 games in November 1936. That year, he also played for the
Can-Am All-Star team. In 1937, he signed with the
Seattle Seahawks, played 88 games, and finished his career as a member of the Lions once more from November 1939 to 1941. He played 140 total career games with the Lions. ==Later life==
