Broncos place Vickerson on IR
The Denver Broncos placed starting defensive tackle Kevin Vickerson on IR with an ankle injury Monday and added fullback Quinn Johnson off waivers from Tennessee.
Vickerson was hurt in the Broncos' loss Sunday to San Diego. He signed a two-year, $4.75 million deal last winter after making a dozen starts last season, his first year in Denver.
Johnson is a third-year pro who's played in two dozen NFL games, including all five of the Titans' games this year. He played his first two seasons in Green Bay, which selected him in the fifth round of the 2009 draft out of LSU.
Acquired in a Sept. 3 trade from the Packers, Johnson was released Friday by Tennessee to make room for the return of fullback Ahmard Hall from a four-game suspension.
