Eastern Kentucky edge defender Noah Spence, who had multiple positive drug tests during his time at Ohio State, sent each of the NFL’s 32 teams the results of the 20 drug tests he has taken since last May, league sources tell Adam Schefter of ESPN.com. According to Schefter, Spence had Eastern Kentucky conduct five drug tests from May through December, then submitted to 15 more – one per week – since January.

In terms of pure on-field talent, Spence is viewed as one of the top pass rushers in this year’s draft class, but his off-field question marks may cause him to slip a little further than he’d like. Still, he continues to be viewed as a first-round pick, and receiving evidence that he has been clean for the last year may make some teams a little more inclined to roll the dice on him.

Here are a few more of today’s pre-draft rumors and updates:

• Despite his significant knee injury, which is expected to sideline him for the entire 2016 season, Notre Dame linebacker Jaylon Smith is still viewed as a potential day-one or day-two pick, according to Adam Schefter (Twitter links). Schefter hears that Smith is likely to be selected before the end of round three, and one NFL head coach even believes the linebacker could come off the board late in the first round.
• The buzz surrounding Louisville defensive lineman Sheldon Rankins has intensified today. Jason La Canfora of CBSSports.com and Matt Miller of Bleacher Report (Twitter links) both have heard that Rankins will be considered as early as No. 4 by the Cowboys, with La Canfora predicting that he’ll end up as a top-10 pick. Tony Pauline at WalterFootball.com has heard that the draft stocks for both Rankins and Mississippi State DT Chris Jones have risen, with teams seeking interior pass rushers.
• Several NFL teams think Ohio State wideout Michael Thomas is being undervalued, and will transition well to the NFL, according to Tony Pauline, who says the Chargers and Bengals are among the teams with interest in Thomas. Pauline adds within the same article that the Vikings aren’t a lock to draft a receiver in round one, and will consider Ole Miss defensive lineman Robert Nkemdiche if he’s available.
• With Notre Dame’s Ronnie Stanley being mentioned in the same conversations as Laremy Tunsil recently, Mike Florio of Pro Football Talk looks into whether or not the Tunsil/Stanley debate is real.
• The NFL is considering Philadelphia and Los Angeles to host the 2017 NFL draft, with Philly emerging as the favorite, tweets Adam Schefter. As Schefter points out, neither of those cities’ teams has a first-round pick in 2017.
• Purdue defensive tackle Ryan Watson has visited, worked out for, or received inquiries from eight teams since his pro day, tweets Aaron Wilson of the Houston Chronicle.
