The 49ers are scheduled to hold a tryout on Tuesday before determining what to do at the kicker position.
Coach Jim Harbaugh said the 49ers will either retain David Akers as their kicker, sign a veteran kicker to take Akers' place on the roster or keep two kickers and have them compete in practice to determine which player will handle the duties in the playoffs.
Akers, 38, is a six-time Pro Bowl kicker who had the worst regular season of his 15-year career. After setting the NFL record with 44 field goals last year, he opened this season with an NFL-record-tying 63-yard field goal against the Green Bay Packers. But this season, he has made just 69 percent (29 of 42) of his field-goal attempts. The NFL average this season is 84 percent.
The two kickers who will take place in the tryout, according to a league source, are:
Cundiff, 32, has kicked in parts of nine NFL seasons with Dallas, New Orleans, Cleveland, Baltimore and Washington. After making just 7 of 12 field-goal attempts to open the season with Washington, he was released.
Prior to that, Baltimore also released him in August. Cundiff missed a potential tying 32-field goal attempt in the closing seconds of last year's AFC Championship game against New England.
In his career, Cundiff is a 75.5-percent kicker, making 139 of his 184 field-goal attempts. He was named to the AFC Pro Bowl team in 2010 after making 26 of his 29 field-goal tries.
Originally a fifth-round pick of the Kansas City Chiefs in 2007, the left-footed kicking 29-year-old Fremont native has bounced around the NFL, CFL and UFL.
His resume includes stints with Kansas City, Toronto Argonauts (CFL), Omaha Nighthawks (UFL), Argonauts, Edmonton Eskimos (CFL), Hamilton Tiger-Cats (CFL) and Carolina. He was also on the offseason rosters of the St. Louis, Washington and Detroit but never appeared in any games with those teams.
Medlock has appeared in just 11 NFL games, including 10 this season with the Panthers. He made 7 of 10 field-goal attempts and all 23 extra points. He went 2 of 4 from 40 to 49 yards, and 0-for-1 from beyond 50. The Chiefs cut him after just one game in 2007, as he made one of his two field-goal attempts.
