Along with Quan Cosby, the Bengals signed undrafted free agent Marlon Lucky. He is the third back running back selected by the Bengals, one of which is full back Fui Vakapuna.

The Huskers team page says about Lucky's senior season.

I-back Marlon Lucky concluded one of the most productive all-purpose careers in Nebraska history with a solid 2008 campaign. The 6-0, 215-pound Lucky finished his career among the top 20 in school history in rushing, while ranking in the top five in receptions and all-purpose yards. The California native was a play-maker for the Nebraska offense since his true freshman campaign in 2005.

Lucky finished his career with 2,393 rushing yards to rank 17th on Nebraska’s all-time rushing list and his 1,019 yards in 2007 was the first 1,000-yard rushing season by an NU back in three seasons. Lucky also caught 135 career passes to rank fourth on that career list, while his 75 receptions in 2007 is a Nebraska season record. Overall, Lucky played in 50 career games with 29 starts and his 4,214 career all-purpose yards ranks fourth in school history.

Lucky started the first 11 games of his senior season before missing the regular season finale with Colorado because of injury. He rotated at I-back with sophomores Quentin Castille and Roy Helu Jr., and the trio of talented backs produced big numbers for a Husker offense that ranked among the top 20 nationally in passing, scoring and total offense.

Lucky finished 2008 as Nebraska’s second-leading rusher with 517 yards and tied for the team lead with seven rushing touchdowns. He also continued to be a factor in the passing game, catching 26 passes, while also triggering the offense on several direct-snap plays. Lucky topped 50 yards on the ground four times during the 2008 campaign, including a 103-yard rushing effort against New Mexico State. His effort against the Aggies included a career-long 58-yard rush. On that run, Lucky became the 24th player in school history to surpass 2,000 career rushing yards. He also threw a 20-yard touchdown pass to Joe Ganz in the game, then added his fourth career TD pass against Kansas off a direct snap from center. Lucky’s 26 pass receptions covered 288 yards and he added his fourth career receiving touchdown in 2008.

Strengths: At least adequate initial quickness off the snap. Can pick and slide down the line before hitting the hole. Patient runner who is willing to allow his blocks to develop. Deceptive agility and straight-line speed. At his best in space as a runner. Cognizant receiver out of the backfield. Shows the body control to handle the tough swing pass and has the ability to track the ball over his shoulder.

Weaknesses: Lacks the elite burst to and through the hole. Upright runner who takes unnecessary punishment. A natural receiver, but struggles to generate separation as a route-runner due to a lack of explosive speed and burst out of his breaks. Willing pass blocker, but marginal toughness or technique in doing so. Has developed into a hard worker. Missed time in 2008 with a turf toe injury.
