Buffalo Bills sign five following minicamp tryout

The Buffalo Bills concluded voluntary veteran minicamp on Thursday. The team invited several unsigned veterans for a tryout during the minicamp, and announced on Thursday afternoon that they had signed five of those players to fortify the back end of their roster.

Perhaps the most intriguing name of the group is fullback Frank Summers. (Check out the pictured hit he put on Andre Brown during the 2010 preseason.) Summers is listed as the only true fullback on the team's roster, and was a fifth-round pick of the Pittsburgh Steelers in 2009. He spent time on the injured reserve list and practice squad before joining the San Diego Chargers practice squad. Without any current competition, he has a shot at the final roster.

Also added were pass rushers Jamie Blatnick and Kourtnei Brown, kicker Chris Koepplin and punter Brian Stahovich. Blatnick was undrafted a year ago and spent part of the season on the Denver Broncos' practice squad, while Brown was with the Washington Redskins in 2012 after being undrafted. Koepplin played two years in Arena League 2.

The Bills now have 70 players on their official roster. The NFL changed the off-season rules in 2012, with each team allowed to carry up to 90 players - including drafted and signed undrafted players - a number Buffalo will surely reach by the end of the month.
