The Lions have started looking at free-agent kickers after rookie Nate Freese missed two more field-goal tries in a Week 2 loss to the Carolina Panthers.
On Tuesday, the team hosted NFL veterans Rob Bironas, Alex Henery and Garrett Hartley for workouts, according to ESPN.
Freese, a seventh-round pick this year, is 2-for-5 on field goals this year with two misses from 49 yards Sunday and a miss from 43 yards in Week 1.
Lions coach Jim Caldwell said Monday the team still was mulling its options moving forward, but gave Freese a vote of confidence, saying he still expects the former Boston College player to be a good kicker.
The Lions could also consider Giorgio Tavecchio, whom they cut after the third exhibition game after he spent the summer competing with Freese.
Bironas spent the past eight years with the Titans, and Henery was with the Eagles the past three years. The Saints cut Hartley during 2013 after he spent parts of five seasons in New Orleans.
The Lions play the Packers at 1 p.m. Sunday at Ford Field.
