Seantrel Henderson’s career at Miami had its share of disappointing moments.

The latest came Thursday when the lineman, projected to be one of the top offensive tackles in this year’s draft, did not finish position drills during his workout at the Hurricanes’ Pro Timing Day which was attended by scouting personnel from 30 NFL teams including the Dolphins and coach Joe Philbin.

“He went there intent to do the bench and position drills but his competitive spirit took over and he did a full combine,” Henderson’s agent David 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.”

According to Levine, Henderson improved on his broad jump and vertical jump from the combine, posting an 8’6” broad and a 28-inch vertical. At February’s combine, Henderson posted a 7’9” broad and a 24-inch vertical. Henderson, who measured 6-foot-7 and weighed in at 339 pounds, was eight pounds heavier Thursday than he was at the Senior Bowl back in January.

“He did everything we needed to see,” said an executive from one NFC team. “He just looked pretty winded at the end, but they put them through it.”

Henderson, who did not speak with reporters after leaving the Greentree practice field, has visits set up with the Dolphins, 49ers, and Steelers next week. He’s also trying to schedule a meeting with the Minnesota Vikings, the team in his home state. He was able to meet with Giants general manager Jerry Reese on Thursday after receiving an IV.

While at Miami, Henderson was suspended multiple times, including once this past season when he violated an unspecified team rule ahead of the Hurricanes’ 45-30 win over Georgia Tech in October. He later told NFL officials his suspensions were linked to marijuana use.

“I’m just being honest with every team and letting them know exactly what the situations were, and that I’m putting all the negative things behind me moving on to the next level,” Henderson said in January. “I want to be a starter and play in the NFL. I’m showing my character. Showing them that I’m responsible, reliable, dependable. I want to keep letting them know all the negative things are behind me.”

While Henderson’s day ended early, several former Miami players — including quarterback Stephen Morris — left Thursday’s workout happy with their respective performances.

Morris, who played through a nagging ankle and Achilles injury last season, didn’t participate in any drills, but focused instead on showing NFL personnel his mobility and his throwing ability.

Since the combine, he’s spent time training with former MLB pitcher-turned-throwing guru Tom House, who has worked with the likes of Tom Brady and Drew Brees. Morris said Thursday the extra training paid dividends.
