Houston cornerback D.J. Hayden worked out for 15 teams Monday, completing the positional drills that a hamstring issue prevented him from finishing at his pro day last month. Rex Ryan was part of a New York Jets contingent that also included the team’s defensive backs coach. Ed Donatell, the secondary coach for the San Francisco 49ers, also was in attendance, along with defensive backs coaches from the Philadelphia Eagles, Tampa Bay Buccaneers, Baltimore Ravens and New Orleans Saints. Hayden worked out for about 45 minutes. In a story on NFL.com, Andrea Kremer details the long odds Hayden faced in his attempt to come back from a life-threatening injury.

D.J. Hayden — who nearly died after he tore a major vein in his heart during a November practice — was the featured attraction at the University of Houston pro day on Monday.

With the pro day for Texas being conducted on Tuesday, and the much-anticipated Baylor pro day behind held on Wednesday, the state of Texas is currently the epicenter for NFL teams scouting potential future pro players.

One player rapidly moving up the charts and catching the eye of talent evaluators is Houston TE Fendi Onobun. Prior to Texas’ pro day on Wednesday, Onobun’s name dominated the breakfast conversation among scouts for the sensational performance he had at Houston’s pro day on Tuesday.

The University of Houston held its pro day Friday indoors on AstroTurf in front of representatives from 17 NFL teams. Twelve players took part in the workout, which included a huge breakfast for scouts at 7:30 a.m. with burritos and fruit in what was an overall great day and a great workout. Gil Brandt also has a report on Nevada’s pro day.
