Despite Siemian's struggles the last several weeks Joseph had been adamant that Trevor would remain the starting quarterback, but drastically changed his tune on Tuesday. The Broncos are coming off their third-straight loss and travel to Philadelphia this Sunday.
Siemian went 19 of 36 for 198 yards and finished with an abysmal 43.5 QB rating.
Osweiler replaces Trevor Siemian, who nearly single-handedly caused the Broncos' skid by recording seven turnovers and compiling a 64.1 passer rating during Denver's losing streak.
Siemian went 8-6 last season when the Broncos missed the playoffs, ending a five-year reign atop the AFC West. Osweiler also went 8-6 last year and 1-1 in the playoffs for the Texans, who traded him in the offseason to Cleveland.
Upon his return, Osweiler held an extraordinary news conference filled with honesty, humility and humor. He threw for 2,957 yards with 15 touchdowns and 16 interceptions.
It's easy to lose in the tidal wave of historic numbers Manning put up as a Mount Rushmore quarterback in the National Football League, but he was once a 20-something who threw 43 interceptions in his first two National Football League seasons combined. They are below.500 for the first time since 2012.More news: Rafael Nadal Ends Year Ranked Number 1 In The World

Vance Joseph stopped short of formally announcing he's about to make a switch at quarterback. Osweiler was released when Kizer was named the starter on September 2 and signed with the Broncos later that day. Siemian earned the starting role following back-to-back training camp duels, but will receive the first demotion of his professional career after accounting for seven of the team's 11 total turnovers over their last three losses.
"Obviously, Paxton is still healing up", Joseph said.
Joseph is scheduled to meet the media Wednesday afternoon and will expand on the decision.
"It's my job to do what's best for the football team", Joseph said Tuesday.
How did we get here? "I think it's fair to examine that position and all positions".
