With the running back battle taking shape and a possible need for a body at safety, the Detroit Lions have waived Mohamed Ibrahim and signed Scott Nelson.

After Saturday's preseason loss to the Jacksonville Jaguars, the Detroit Lions made a roster move on Sunday. Running back Mohamed Ibrahim has been waived/injured, and safety Scott Nelson has been signed.

Ibrahim, an undrafted rookie out of Minnesota, had been an easy darkhorse to make the Lions' 53-man roster as the third or fourth running back. But he was injured during the preseason opener against the Giants and he has not returned since. He had clearly fallen behind in the position battle. Craig Reynolds appear to have taken a lead in the battle to be the No. 3 running back, with Benny Snell, Jermar Jefferson and Devine Ozigbo the remaining competitors now.

If Ibrahim clears waivers, he would revert to the Lions' injured reserve list. Then either his 2023 season would be over, or he could be released with an injury settlement and become a free agent.

Detroit Lions add safety Scott Nelson amid injury concerns

Ifeatu Melifonwu and Saivion Smith both left Saturday's game against Jacksonville with injuries, casting their status for the preseason finale against the Carolina Panthers into doubt. Enter Nelson.

Nelson (6-foot-2, 205 pounds) went undrafted out of the University of Wisconsin in 2022. He signed with the Seattle Seahawks, and spent about a month on their practice squad before they released him and the Pittsburgh Steelers signed him. He was on and off the Steelers' practice squad the rest of the season. He signed a futures deal with the Steelers after the season, and he was released by them in June.

Nelson is a Detroit native, and graduate of Jesuit High School.

Nelson will probably have a hard time sticking with the Lions for very long. Safety is a deep spot for them, and there are others likely more in line for a practice squad spot (Brandon Joseph, Brady Breeze). But he's in line for an opportunity to put some significant playing time on tape in the preseason finale, and that could turn into an opportunity for him somewhere.
