The NFL draft starts on April 23. As draft candidates for the Lions bubble up over the next few weeks, I’ll post my health concern levels for select prospects. The concern level will range from 0 (no concern) to 5 (might be worth the risk if the reward is high) to 10 (take him off your board, Brad).

Here are 3 EDGE players who might interest the Lions. Two of them have been standouts at the Senior Bowl this week.

Quick summary of concern levels

Akheem Mesidor, EDGE (25): foot surgery, elbow, age - 6/10 concern
TJ Parker, EDGE (22): knee surgery - 3/10 concern
Derrick Moore, EDGE (23): new hamstring - 2/10 concern

Akheem Mesidor, EDGE (25) - Miami

Projected round 1. #18 on Daniel Jeremiah board Jan 27. Mocked to Lions in 1st round by Jeremiah.

Concern level 6/10

2025: 15/16 games. Missed 1 game due to foot injury. Elbow injury during playoff semifinal but returned the next game.
2024: 13/13 games.
2023: Played 3 games. Torn ligaments in foot requiring surgery which ended his season.
2022: 11/12 games
2021: 13/13 games
2020: 10/10 games

A foot surgery for torn ligaments is definitely a concern going forward with one possible diagnosis being a Lisfranc. Any kind of foot surgery could be a chronic issue given the trickiness of the complex small anatomy. It’s reassuring however that he has played 2 strong seasons since the surgery.

The elbow is also worth looking into since he only played in one game (national championship) after that. Both of these issues will need to be fully vetted by medical.

His older age is also a significant factor. Mesidor compiled 52.5 TFL and 35.5 sacks in 6 years of college. Yes, 6 years.

TJ Parker, EDGE (22) - Clemson

Projected round 2. #38 on Daniel Jeremiah board Jan 27

Concern level 3/10

2025: 12/13 games. Opted out of bowl.
2024: 14/14 games.
2023: 13/13 games. Knee surgery after season.

No details on the knee surgery but a common cause for a surgical knee issue that can be temporarily played through is minor cartilage damage - either meniscus or articular. It’s reassuring that he played 2 healthy seasons after the surgery. Any loss of cartilage has the potential to cause issues down the road though. On the positive side is his young age.

Parker was very productive in college with 41.5 TFL and 21.5 sacks in just 3 seasons. Some have him as the top player at the Senior Bowl…

Derrick Moore, EDGE (23) - Michigan

Projected round 2-3.

Concern level 1/10. Post-combine 2/10.

2025: 12/13 games. Opted out of bowl game
2024: 12/13 games. Missed game with unspecified injury.
2023: 15/15 games. Won national championship.
2022: 14/14 games.

Combine update: Strained hamstring prior to combine. Medical will need to make sure that the injury is only a hamstring, and nothing more serious. If the hamstring prevents workouts at the combine, then a subsequent pro day will be important to prove health. Moore has 2 months until the draft which should be enough time to heal up and do some workouts.

Moore has been very reliable in his college career. There are no concerns heading into the draft except ideally being 1-2 years younger.

Moore had 24.5 TFL and 21 sacks in college. Here he is showing his power at the Senior Bowl…
