The Bears signed veteran RB Lorenzo Booker to a one-year deal on Tuesday and released RB Alvester Alexander.
Booker, a third-round pick in 2007 by the Dolphins, was with the Vikings the past two seasons. As Minnesota’s kickoff returner in 2010 and ’11, he had 37 returns for 879 yards.
Last season, Booker rushed for 52 yards on 13 carries and had eight catches for 82 yards.
Alexander was a UDFA out of Wyoming.
