The Browns re-signed undrafted rookie running back Jamaine Cook and waived undrafted rookie safety Kenronte Walker, the team announced this morning.
Cook was added to bolster the depth at running back, a position decimated by injuries.
Dion Lewis entered training camp as the third running back on the depth chart, but he will undergo surgery on a fractured left fibula he suffered Thursday night in an exhibition win over the Detroit Lions. He could be out for the season.
Montario Hardesty, who was listed as starter Trent Richardson’s primary backup, underwent arthroscopic knee surgery Thursday, a procedure that usually requires at least a month of recovery time. Hardesty has had torn anterior cruciate ligaments repaired in both knees.
The 5-foot-9, 210-pound Cook originally signed with the Browns as an undrafted free agent April 30 and was waived May 21. Cook finished his career at Youngstown State University second in school history with 4,052 career rushing yards on 811 carries to go along with 39 touchdowns. He had more than 1,200 rushing yards and at least 11 rushing touchdowns in each of his three seasons as a starter.
A native of Middleburg Heights, Cook graduated from Midpark High School, which is just a few miles away from the Browns’ training facility.
"I definitely grew up a Browns fan," Cook said in May. "I played in their backyard a few minutes away. But I don't want that to be a distraction. I've got a goal I want to accomplish, and I want to work.
"This is obviously a blessing. I just love being here. This is my comfort zone because this is where I'm from. It makes things much easier."
In May, the Browns signed Walker, who was a two-year letterman at safety at the University of Missouri. He was listed fourth on the depth chart at strong safety.
