Former University of Miami offensive tackle Seantrel Henderson tested positive for marijuana at the NFL Scouting Combine in February, ESPN reported.
Henderson is considered a very talented lineman but had off-field issues and suspensions related to marijuana during his college career. He also failed to complete his Pro Day workout. According to ESPN, he quit. Henderson's agent, David Levine, said Henderson got tired and could not finish the positional drills.
"He went there intent to do the bench and position drills but his competitive spirit took over and he did a full combine," Levine told the Sun-Sentinel. "At the end of the workout he got dehydrated, started getting a super bad headache, felt like he was going to throw up and didn't do the last two O-line drills."
Henderson, who is 6-feet-7 and 339 pounds, is NFLDraftScout.com's 14th-ranked tackle and No. 157 overall prospect. He is projected as a fifth-round pick in this week's draft.
Henderson has had known visits with the Miami Dolphins, Pittsburgh Steelers and San Francisco 49ers.
Henderson continues to be a tough prospect to project because he is extremely talented for a player of his size and strength, but the potential hasn't necessarily translated to the field.
He was a five-star high school recruit and widely believed to be one of the best offensive linemen to enter the college ranks in recent years. Henderson chose to play at Southern Cal, but changed his mind once the Trojans were slapped with a two-year postseason ban, deciding instead to enroll at Miami.
He started nine games as a true freshman at right tackle for the Hurricanes, earning Freshman All-American honors. Henderson was suspended for the season opener in 2011 for violation of team rules and missed several other games because of offseason back surgery. He started only a pair of games in '11, both at right tackle, but enjoyed a solid 2012 with seven starts and All-ACC honorable mention honors from league coaches.
Henderson was suspended yet again last season for a violation of team rules, missing the Georgia Tech game. He finished the year starting eight of the 12 games he appeared in at right tackle.
Henderson is a mountain of a man and has enough foot quickness to hold his own on the edge, but the latest report of a failed drug test may drop a player with first-round talent all the way out of the draft. After admitting at the Senior Bowl that he had been suspended for failed marijuana tests multiple times in college, Henderson certainly continues to hurt his own cause by reportedly failing yet another test - and one he knew was coming months in advance.
