Henderson, a 6-foot-8, 300-pound tackle, recently made his first official visit, when he traveled to Ohio State for the Buckeyes defeat to USC on Sept. 11. Henderson's short list remains Ohio State, Florida, Oklahoma, Southern Cal, Notre Dame, Minnesota and possibly a late, wildcard entry in Miami.
Henderson's next visit is scheduled for Notre Dame Oct. 11. Henderson's former prep teammate, receiver Michael Floyd, plays for the Irish. Floyd, however, recently underwent surgery for a broken left collarbone and will miss the remainder of the season.
Henderson also has scheduled a visit to Southern Cal Nov. 27. He hasn't set dates for his remaining two visits (players are permitted five under NCAA rules).
Henderson was one of 30 players nationally recently named to the watch list for the 2010 U.S. Army Player of the Year Award. Past winners include Kevin Jones (Chicago Bears), Lorenzo Booker (Florida State), Chris Leak (Florida), Adrian Peterson (Minnesota Vikings), Ryan Perrilloux (Jacksonville State), Mitch Mustain (USC), Jimmy Clausen (Notre Dame), Terrelle Pryor (Ohio State) and Bryce Brown (Tennessee).
Scanlan says Henderson hasn't let the recruiting pressures affect his performance.
"We are 4-0 in the conference (Suburban East) with some tough games coming up, but it beats 0-4," Scanlan chuckled and told FanHouse Monday morning.
"We have a nice balance between running and throwing. Of course, we have the franchise - Seantrel. He is playing well. This is probably as good a start of a season that he has ever had. I think he has been able to stay focused. He's real responsible. He takes care of (academic work). I think he has been doing a great job."
Henderson has started every game at left tackle for Cretin-Derham since his sophomore season (freshman aren't allowed to play varsity for the Raiders) and he has allowed just one sack.
