Kicker Jason Hanson is not a lock to return to the Lions for his 20th season even though he has two years remaining on his contract. Lions general manager Martin Mayhew said kicker is one of the roster positions that has not been set for the 2011 season.

Hanson underwent knee surgery for his second straight training camp in August and then was forced out for the remainder of the season with a knee sprain that happened on Nov. 7.

The 40-year-old kicker has played 19 years with the Lions.

Dave Rayner (Michigan State, Oxford High) was signed and kicked well in the final eight games including two pressure field goals to win the game in overtime in Tampa and a 55-yarder in Sunday’s win over the Vikings.

Well enough to replace Hanson?

“I don’t know if I would say fight for his job. (Hanson) is probably a first-ballot Hall of Fame type of kicker,’’ Mayhew said. “He’s had a lot of success here, he had a tough run with injuries this season and we’re still sort of formulating our plans for the roster this year at a lot of different positions, but kicker is one of them.’’ (Follow me on Twitter @PaulaPasche.)
