Roughly four and a half months removed from surgery to repair the injury, Hahn has lived up to his word. Penn State is holding a Pro Day on campus Tuesday, and Hahn is ready to participate on a limited basis.
He will be measured, do the bench press, take the Wonderlic Test and hopefully have a chance to meet scouts and do a few drills.
I'm almost five months out [from surgery], Hahn said. I've been running the 40-yard dash, but I'm not running the time I was running before the injury. So me and my agent decided not to run it tomorrow because that will be a number that follows me. Hopefully some teams will like me and give me a chance to work out for them in a month.
Prior to his injury, Hahn said he topped out in the high 4.6-second range in the 40-yard dash and consistently ran 4.7s. Those are good times for his size (he played at 6-foot, 230 in 2007).
He has managed to get his 40 time back to within a couple of tenths of where he was before the injury, but feels in a short while he'll be as good as ever.
I recently ran a 4.9, which is really good for where I am, he said. But some of these scouts may not realize I'm only four and a half months out from an ACL injury.
Rather than heading to a training facility aimed specifically at preparing athletes for the NFL Draft, Hahn spent his winter at Penn State. He felt more comfortable being around the doctors and training staff who helped him during his early recovery from the injury.
He has had plenty of time to aggressively attack his rehabilitation because he is not taking any classes this semester. A recreation, parks and tourism management major, he is doing an internship at the local YMCA as the final step to earning his degree.
This has worked out very well for me, he said.
Before the injury, Hahn felt he had an outside chance of earning a trip to the NFL Combine. But because that did not materialize, he views Tuesday's Pro Day as a chance to do more than simply show teams where he is physically.
I'm looking forward to sitting down with the scouts, being able to interact and talk with them, he said.
Hahn also hopes to do a little bit of running, though not for time or to show his agility. Despite being limited to running in a straight line now, he'd like to do some basic pass patterns to show off his ability to catch the ball.
During his career with the Nittany Lions, Hahn had nearly as many catches (27 for 214 yards and two scores) as carries (30 for 134 yards and one TD).
The key Tuesday is doing enough to keep the scouts interested so he can get a few more workouts before the April 26-27 NFL Draft without risking a setback in his recovery because he is overdoing things.
I'm in the best shape I can be in at this point, Hahn said. I've done everything I can and have heard great reports from the doctors. As far as a full recovery is concerned, that's not going to be a problem.
