ALLEN PARK, Mich. (AP) - The Detroit Lions have officially signed kicker David Akers. The team didn't disclose terms of the contract Tuesday. Akers and the Lions agreed to a deal last week, a day after kicker Jason Hanson announced his retirement. The 38-year-old Akers was released last month by the San Francisco 49ers after he followed up a record-breaking season with shaky results. The four-time All-Pro and six-time Pro Bowl kicker made just 29 of 44 field goals last year after setting single-season league records with 44 field goals made and 52 attempted in 2011. Akers has made 367 of 453 field goals in his career with Washington, Philadelphia and San Francisco. The 42-year-old Hanson said he is retiring primarily because of pain in his non-kicking left heel.
