Veteran offensive tackle Seantrel Henderson, released by the Texans last year, worked out for the Redskins on Wednesday (Twitter link via ESPN.com’s Field Yates). Henderson could be a candidate for the 90-man offseason roster, giving the Redskins an interesting depth candidate for the year ahead. 
Early in his career, he started in 26 contests for the Bills between 2014 and 2015 and proved to be a proficient blocker. However, things took a turn in later seasons.
Henderson was hit with a ten-game substance abuse policy suspension in 2017, his second ban after previously serving a four-game suspension. For his part, Henderson says he was only using marijuana to help treat symptoms of his Crohn’s disease.
Henderson hooked on with the Texans in 2018 and earned a re-up for 2019. But, after Week 1, the 28-year-old was benched, then waived in November. Henderson went on to audition for the Bills, Seahawks, and Ravens, but was unable to find a new club.
The Redskins’ O-Line, without Trent Williams, still managed to perform decently as a unit. This year, new head coach Ron Rivera and new OL coach John Matsko will look to build upon that and they’ll have a healthy Brandon Scherff to help the cause.
