18. Jewel Hampton, Running Back, San Francisco 49ers
Hampton was brought into the mix to provide depth after the injuries to Kendall Hunter and Brandon Jacobs. The running back depth on the 49ers' roster means he has little chance of staying on with the team for the long term.
17. Tony Jerod-Eddie, Defensive Line, San Francisco 49ers
San Francisco promoted Jerod-Eddie in Week 17 because Justin Smith was still dealing with injury issues. Jerod-Eddie didn't record a single stat in during his call-up.
16. Adrian Hamilton, Linebacker, Baltimore Ravens
Baltimore added Hamilton to the roster prior to Week 16 because the linebacking corps was dealing with a handful of injuries. He saw limited action, and it's very likely he isn't on the active roster for the Super Bowl.
15. Omar Brown, Safety, Baltimore Ravens
Brown was a late-season addition who saw some action on special teams. It's unlikely he makes an impact during the Super Bowl.
14. Asa Jackson, Cornerback, Baltimore Ravens
Jackson didn't see much action this season, but he still has a future with the team. He's a good athlete who just needs to improve his technique and gain more experience. However, he faces a tough road ahead. The Ravens have good depth at the cornerback position, so Jackson will need a strong offseason to earn playing time.
13. Trenton Robinson, Safety, San Francisco 49ers
Robinson began the season seeing playing time on special teams. However, he committed a few costly penalties and lost his opportunity to make an impact. This resulted in him not seeing any action after Week 3.
12. Cam Johnson, Linebacker, San Francisco 49ers
The 49ers selected Johnson in the seventh round, even though he was still dealing with an offseason injury. Johnson's addition gives the team depth at the linebacker position, and he is someone who could develop into another pass-rushing threat. He saw limited action in the team's final two games but failed to record a stat.
11. Gino Gradkowski, Guard/Center, Baltimore Ravens
Gradkowski was drafted in the fourth round and serves as a backup at both the guard and center positions. With Matt Birk nearing the end of his career, Gradkowski will likely get a chance to compete for a starting job in the near future.
10. Joe Looney, Guard, San Francisco 49ers
Looney suffered an injury in training camp which pushed him down the depth chart. Before the injury, he was among those competing for the starting right guard spot. Alex Boone ended up winning the job, and he has performed well enough to solidify his hold on the position. This means Looney will be looking at a backup role heading into next season.
9. DeAngelo Tyson, Defensive Line, Baltimore Ravens
The Ravens rotated Tyson in along the defensive line from time to time. He served an important role because of the injuries suffered by Pernell McPhee, Haloti Ngata and Terrence Cody. Having someone like Tyson capable of stepping in and holding his own is key to a team's ability to navigate the long season.
