The Lions continued to work on the lower portion of their roster, adding a pair of players Friday.

The Lions cut running back Allen Ervin on Thursday, and left his roster spot open until Friday, adding kick returner Glenn Holt after their waiver claim went through in the afternoon. Holt was waived by the Vikings Thursday.

Friday, the Lions dropped wide receiver Billy McMullen, and replaced him with linebacker Rufus Alexander. A cousin of former Lions safety Gerald Alexander, Rufus Alexander was a sixth-round pick of Minnesota in 2007, but spent the 2007 and 2008 seasons on the practice squads of the Vikings and Colts.

Holt, who spent three seasons with the Bengals before signing with Minnesota, has a career 24.3-yard average on 122 kickoff returns.
