ORCHARD PARK, N.Y. (AP) The Buffalo Bills have reached deals to sign 14 undrafted rookie free agents, including Oklahoma linebacker Eric Striker, who provided an emotional speech to family and friends after not being selected last weekend.

At 6-feet and 221 pounds, Striker went undrafted despite being a three-year starter, and had had 46 1/2 tackles for a loss and 23 sacks. On Saturday, a video emerged of Striker tearfully thanking family and friends for being with him through the draft process, while adding that he's proven himself before.

The Bills also agreed to sign Kansas State fullback Glenn Gronkowski, the younger brother of New England Patriots star tight end Rob Gronkowski. Other notable additions were Marshall receiver Davonte Allen and Arizona State receiver Gary Chambers.
