The Indianapolis Colts have signed rookie fullback Ryan Mahaffey off the Baltimore Ravens practice squad, the Ravens announced on Wednesday. Signed by the Ravens as an undrafted free agent out of Northern Iowa, the 6-foot-2, 257-pound Mahaffey caught one pass for four yards during the preseason. After clearing waivers following the final roster cuts, Mahaffery was signed to the Ravens' practice squad. Indianapolis has been without a true fullback after placing Chris Gronkowski on injured reserve in Week 8. Source: Mac's Football Blog
