CLEVELAND -- The Browns have re-signed free agent rookie running back Jamaine Cook, a move made necessary by injuries to Dion Lewis and Montario Hardesty.
Cook was with the Browns earlier this year before he was waived on May 21. The 5-foot-9, 210-pounder is the second-leading career rusher in Youngstown State history.
In the past few days, the Browns lost Lewis to a broken leg and Hardesty underwent knee surgery. Lewis is scheduled to have an operation to repair the fibula he broke Thursday night against Detroit. He could be lost for the season.
Hardesty is expected to be sidelined for at least one month.
Those injuries have given Brandon Jackson a chance to solidify a backup spot behind starter Trent Richardson and perhaps be used in third-down situations.
