OWINGS MILLS, Md. -- The Baltimore Ravens made a change at their No. 3 running back spot on Saturday.

Baltimore promoted former Seattle Seahawks back Alex Collins from the practice squad and waived Jeremy Langford, the former Chicago Bears back who was just signed to the 53-man roster Thursday.

A 2016 fifth-round pick of the Seahawks, Collins is one of only three running backs in SEC history to rush for 1,000 or more yards in their first three seasons (Herschel Walker and Darren McFadden are the others). He gained 125 yards on 31 carries in 2016 but finished his rookie season strong with 106 yards on 21 attempts over the last three games.

Collins, 23, reported in better shape this year, dropping 13 pounds to weigh 204. But the Seahawks waived Collins at the end of the preseason.

In another move, the Ravens promoted cornerback Tony McRae from the practice squad and placed cornerback Sheldon Price (concussion) on injured reserve.
