Four lesser-known prospects who could be late-round draft choices took part in workouts hoping to impress NFL teams.

Representatives of 27 NFL teams attended the Coastal Carolina pro day to watch CB Josh Norman work out, and OT Matt McCants showed his stuff at Alabama-Birmingham.

Safety Matt Johnson recovered from a biceps injury in time to impress at Eastern Washington’s pro day, and WR Toney Clemons stood out at Colorado’s pro day.

David Gonzales and Alex Hoffman-Ellis did well at Washington State’s pro day, while Korey Toomer drew a crowd at Idaho.

Two well-thought-of offensive line prospects were the center of attention when Georgia held its pro day on March 5.

There were 25 NFL teams represented at a workout on Wednesday that was specifically designed for teams to get a look at Oklahoma wide receiver Ryan Broyles, who’s been recovering from a knee injury.

There were 24 teams present — including Pittsburgh Steelers offensive coordinator Todd Haley — when Penn State held its pro day on March 14.

Luke Nix was a three-year starter on the offensive line at the University of Pittsburgh, and many from the 22 teams present at the school’s pro day were on hand to check this player out. Nix figures to be a late third-round or early fourth-round selection in the 2012 NFL Draft.

Dontari Poe put on a show at the NFL Scouting Combine, most notably leading all participants in the bench press, doing 44 reps of 225 pounds.

So, it came as no surprise when the defensive tackle prospect opted to stand on his eye-popping combine performances when Memphis held its pro day on March 22.

There were 15 NFL teams present, including Arizona Cardinals assistant head coach/offensive line coach Russ Grimm, when Purdue University held its pro day indoors on FieldTurf on March 9.

Two offensive linemen who did not participate at the NFL Scouting Combine, and a kicker who was at Lucas Oil Stadium in late February, were the players of note working out in West Lafayette, Ind.

Columbia University hasn’t had a player drafted since Marcellus Wiley in 1997, and offensive tackle Jeff Adams could break that streak in late April.

Portland State had a player selected in the 2011 NFL Draft — tight end Julius Thomas in the fourth round — and the Football Championship Subdivision school could produce another draft pick in late April.

Despite not having a player present at the NFL Scouting Combine, East Carolina features two potential late-round draft picks.

Two up-and-coming prospects — QB Dominique Davis and OT Steven Baker — give the Pirates their best shots at having athletes selected by NFL teams in late April

The University of Toledo hasn’t exactly been a hotbed for potential pro football players, and hasn’t produced a draft pick since 2008 (when two Rockets — OT John Greco and RB Jalen Parmele — were selected).

One Toledo player — WR Eric Page — was invited to participate at the NFL Scouting Combine. Page also represents Toledo’s best shot at having a player selected in April.

Though Connecticut held its pro day toward the end of the normal circuit, 18 teams were still on hand to take in the Huskies’ workout on March 28.
