The 49ers are in the market for some front seven depth. Former Falcons defensive end Tyson Jackson auditioned for the team on Tuesday, a source tells Ian Rapoport of NFL.com (on Twitter). 
The former No. 3 overall pick was released by Atlanta at the outset of free agency. With $8.5MM and two years to go, it was an easy choice for Atlanta given the way that Jackson played in 2016.
Last year, Jackson finished out with 13 total tackles and two pass deflections in 16 games (seven starts). The advanced statistics at Pro Football Focus rated him as just the No. 67 interior defender in the NFL out of 127 qualified players. His grades for run defense, pass rush, and coverage were all poor in his 389 total snaps.
Jackson failed to record a sack in any of his three seasons with the Falcons, but he was an effective player while with the Chiefs. The Niners are now assessing whether he can be a worthwhile pickup for their team.
