Former Patriots running back and return specialist Mack Herron died Sunday in Chicago. He was 67.

“Mini Mack,” as the 5-foot-5-inch, 175-pounder was known, played for the Patriots for 2½ seasons (1973-75).

Herron set a number of franchise return records and in 1973 was second in the NFL to O.J. Simpson with 1,839 all-purpose yards.
