According to Schefter, Dockett is choosing between the 49ers and Cardinals, even though the Rams and Seahawks are interested as well.
According to Kent Somers, the Cardinals are believed to have offered Dockett a one-year deal worth a minimum of $2.5 million and could increase to around $4 million through play-time and production incentives.
Dockett, 33, sustained a torn ACL and MCL that he sustained during a preseason practice back in August.
In 2013, Dockett recorded 46 tackles and 4.5 sacks over the course of 16 games for the Cardinals. That year, Pro Football Focus rated him as the No. 30 defensive end in a 3-4 defense out of 45 qualifying players.
