The Lions signed punter Drew Butler Friday, adding someone who can give Sam Martin some time off during training camp.
Butler punted for the Pittsburgh Steelers as an undrafted rookie in 2012, but was cut before the start of the 2013 season. He also spent this offseason with the Chicago Bears.
Butler averaged 43.8 yards on 77 punts with the Steelers in 2012.
Martin, a fifth-round pick in 2013, played well as a rookie and ranked in the top 10 in most statistical categories.
Butler will have a chance to compete in camp, but it will be difficult to unseat Martin. The coaches might just want an extra leg for punt return practice to avoid wearing out Martin.
To make room for Butler, the Lions waived former Oklahoma safety Gabe Lynn, an undrafted rookie they signed after the draft.
