Former No. 3 overall pick Tyson Jackson is visiting the Texans and will work out for them, Ian Rapoport of NFL.com hears (on Twitter). The Texans are in desperate need of defensive line help after losing J.J. Watt and Whitney Mercilus to season-ending injuries, so Jackson could be a natural fit. 
Jackson was cut loose by the Falcons at the outset of free agency. With $8.5MM and two years to go on his deal, it was an easy choice for Atlanta given his disappointing performance in 2016.
Last year, Jackson had just 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 atrocious in his 389 total snaps.
Furthermore, 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. He may not be the world-class player NFL scouts thought he might be in 2009, but he could help to fill a major need in Houston.
