ANN ARBOR, Mich. --Michigan redshirt sophomore linebacker Jake Ryan is wearing the No. 47 jersey, unretired Saturday before No. 19 Michigan's game against Air Force.
Ryan had five tackles in the season-opener against Alabama.
Bennie Oosterbaan's family was honored on the field before the game, presented with a framed No. 47.
This is the second Legends Patch awarded. Former Michigan receiver Desmond Howard was given the designation last season and his No. 21 jersey was first worn by Junior Hemingway and then this season by fifth-year senior Roy Roundtree. Oosterbaan's No. 47 is the first of four previously retired jerseys to be put back into circulation this season by Michigan.
Oosterbaan is one of two three-time All-Americans at Michigan, earning the honor in 1925, 1926 and 1927. After playing at Michigan, he started coaching at the school, first as an assistant for Fritz Crisler and then as the Michigan head coach from 1948 to 1958.
In that time, he had a 63-33-4 record and won the national championship in 1948. His teams also won or shared three Big Ten titles.
Oosterbaan was also a two-time All-American in basketball in 1927 and 1928.
