The Cleveland Browns plan to sign running back Jamaine Cook today following a tryout and running back Dion Lewis' broken fibula, according to a league source.
Lewis is expected to undergo surgery and will be placed on injured reserve.
The Browns cut defensive back Kenronte Walker with the addition of Cook.
This marks Cook's second stint with the Browns after being waived earlier this year when the team signed Miguel Maysonet.
The former Youngstown State standout rushed for 4,052 yards in college with 39 touchdowns.
Cook rushed for more than 1,200 yards and 11 touchdowns in three seasons as a starter, including 1,279 yards and 15 touchdowns last season.
