Kumerow agreed to re-sign with the Bills on Thursday, Mike Garafolo of NFL Network reports.
Kumerow was released by the Bills on Thursday, but the move was simply made to free up some cap space. The 30-year-old dealt with an undisclosed injury last week but appears to have moved past the issue as mandatory minicamp draws to a close. Kumerow has played primarily on special teams during his time in Buffalo, but he'll compete for a larger role in the Bills' offense during training camp this year.
