Q: Question: How many teams belong to the league that Macon left the Chicago Bears to play for in 1954? Passage 1:Macon was drafted in the second round (twentieth selection) of the 1952 NFL Draft by the Chicago Bears and became the first African-American player on the team; he spent two years as a halfback and return specialist. He was the second African-American to be drafted by the Bears; the first, George Taliaferro, was drafted by them in 1949, but chose to play in the All-America Football Conference. With the Bears, Macon rushed for 324 yards and two touchdowns on 70 attempts while catching 14 passes for 49 yards and two touchdowns. On 22 kick returns, he averaged 30.5 yards per return and 5.9 yards on 24 punt returns. He left the Bears in 1954 to play for the Calgary Stampeders of the Canadian Football League. Bears coach and owner George Halas was not pleased about his departure, blackballing Macon and suing him for $100,000. As a result, the Bears refused to acknowledge Macon being on the team. After being out of football for two years, which he spent as a longshoreman, Macon joined the Hamilton Tiger-Cats in 1957 before leaving in 1959 to resume his longshoreman career, but later joined the Oakland Raiders of the American Football League in 1960. With the Raiders, Macon was converted to defensive back, and was tied for second in the league with nine interceptions, which earned him All-Pro honors.
 Passage 2:Engelbach was born in Spain, at Jerez de la Frontera, to English parents. During the 1890s she studied in London at the Westminster School of Art and at the Slade School of Art before completing her studies in Paris. Engelbach had works shown at the Laing Art Gallery in Newcastle and at the Paris Salon. In 1901 she had a picture shown, under her maiden name, at the Royal Academy in London. She was awarded a bronze medal at a Women's International Art Club exhibition held in London. In 1902 she married a C.F.R Engelbach and withdrew from a full-time art and exhibition career to raise a family. Engelbach returned to painting in the late 1920s and had a solo show at the Beaux Arts Gallery in 1931. She went on to resume exhibiting at both the Royal Academy and the Paris Salon and also with the Royal Institute of Oil Painters and the National Society of Painters, Sculptors and Gravers/ Printmakers and became a member of the latter two societies. The Goupil, Tooths and Lefevre galleries were among the commercial concerns that showed her work. Originally Engelbach was a portrait painter but later became a specialist flower painter who also painted landscapes. Her painting Roses, from the 1930s, is held in the Tate collection. A memorial exhibition for Engelbach was held at the Leicester Galleries in 1951.
