It's not the same as signing an undrafted free agent contract, but it sounds as if former Pitt running back Zach Brown could be trying out for the Buffalo Bills.
I haven't been able to confirm this anywhere else, but ESPN.com's Andrea Adelson has him listed in her post on Big East players signing deals or participating in tryouts.
Personally, I had expected the next name to be signed or headed for a workout to be defensive lineman Myles Caragein, but still good to hear another Pitt player getting a shot at getting on an NFL roster.
Brown, of course, would join former Pitt coach Dave Wannstedt in Buffalo should he make the team.
Got to think of him as a long shot at this point. He wasn't drafted and apparently wasn't offered a contract by anybody else. Even if he impresses in the tryout, he'd still need to make it through camp.
Brown ended up being a good pick-up for Pitt. He played behind Ray Graham last year, but stepped in and filled a big role after Graham went down to injury. Brown had his own injury issues later to deal with, but when he played, he was pretty effective. He had some good games for the Panthers, including his nine-catch, 100+ total yard-performance against UConn and nearly 100 total yards against Cincinnati the following week.
