This shapes up as the busiest week of the preseason for the Denver Broncos, who have open practices Monday through Wednesday, with Wednesday morning's session being a joint practice with the 49ers.
The two teams then hook up in the Broncos' first home game of 2016 on Saturday night.
Denver comes into the San Francisco game fresh off that 22-0 shutout of the Chicago Bears, which happens to have been the ninth shutout by the Broncos in team preseason history. Three of those came with the 49ers as the victims, 20-0 in 1977, 21-0 in 1978 and 34-0 in 2014.
