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.

LSU running back Spencer Ware worked out on campus on Friday, April 29. Ware ran indoors and on FieldTurf, and wasn’t measured at the workout. He did weigh in at 229 pounds, though. As for his numbers, he ran the 40-yard dash in 4.62 and 4.63 seconds. He posted a 34 inch vertical leap and a 10-foot-1/2 inch broad jump. In the short shuttle drill, he clocked in at 4.35 seconds, and completed the three-cone drill in 7.07 seconds. He opted not to lift, as he already had at LSU’s pro day. Ware had a good workout on the day, and caught the ball exceptionally well.
