Clemson DE Da'Quan Bowers - Played through a partial meniscus tear late in the college season and had the knee scoped sometime in January. He's tentatively expected to run at the Combine.
UPDATE: Bowers will only lift in Indy. He will run at Clemson's Pro Day in late March.
Notre Dame TE Kyle Rudolph - On October 15, underwent season-ending surgery on his right hamstring. He'll be available for inspection at the Combine, but won't run before the Irish's April 7 Pro Day.
North Carolina DE Robert Quinn - Had a benign tumor removed from his brain as a high school senior. Quinn has long since been medically cleared, but one report over the weekend claimed NFL teams are "really getting scared off" by the four-year-old surgery.
USC OT Tyron Smith - Underwent arthroscopic knee surgery in January after playing through the injury down the stretch. Smith is expected to wait for USC's March 30 Pro Day to run for scouts.
Ohio State DE Cameron Heyward - Heyward underwent Tommy John surgery on his left elbow in early- to mid-January. He should be able to run, jump, and perform agility drills in Indianapolis.
Boston College LB Mark Herzlich - Overcame Ewing's Sarcoma, a rare form of bone cancer, as a college junior. Herzlich had a rod inserted into his left leg during chemotherapy, however, and struggled in coverage as a senior. He can expect plenty of poking and prodding.
North Carolina LB Bruce Carter - Tore his left ACL on November 20 and had reconstructive knee surgery on December 14. Carter will attend the Combine only to weigh in and meet with teams.
Virginia CB Ras-I Dowling - Dowling skipped the Senior Bowl to rehab hamstring, ankle, and knee injuries suffered during a disappointing senior year. His status for the Combine is questionable.
Southern Miss WR DeAndre Brown - Suffered a compound tibia and fibula fracture in the 2008 New Orleans Bowl, and last year missed seven games with an injury coach Larry Fedora called a "lower leg strain," but did not detail further. Agent Bus Cook insists Brown can run a 4.4 in Indy.
Miami RB Graig Cooper - Tore his ACL in the 2009 Champs Sports Bowl and lost his starting job as a senior. Also missed three games in 2010 with a high ankle sprain. Cooper participated in January's Senior Bowl, but whether he's truly 100 percent is unclear.
Villanova T/G Ben Ijalana - Missed the Senior Bowl due to "double hernia surgery" after playing the last six games of his college career with the injury. He's expected to be OK for the Combine.
Kansas State RB Daniel Thomas - Sat out January's Senior Bowl with a hamstring injury, the extent of which was unknown. Thomas should be 100 percent by now.
Eastern Washington RB Taiwan Jones - In December, underwent surgery to repair a fractured fifth metatarsal in his left foot. Jones also injured both shoulders in college, had a sports hernia, and broke his fibula. The small-schooler will wait for Hawaii's March 31 Pro Day to run for scouts.
Ole Miss DE Kentrell Lockett - Applying for a sixth year of college eligibility after tearing his left ACL on September 25. Lockett is also believed to be dealing with a heart condition.
Purdue WR Keith Smith - Tore his right ACL and MCL on September 11, and didn't have surgery until October 18. Like Lockett, Smith is petitioning the NCAA for a sixth year of eligibility.
Utah State CB Curtis Marsh - Missed the Senior Bowl with a recurring hamstring injury. A former running back, Marsh should be ready to participate in all drills at the Combine.
Oregon State DT Stephen Paea - Tore his right meniscus at the Senior Bowl and had the knee scoped on January 27. Paea is considered questionable to perform lower-body drills in Indy.
UPDATE: Paea announced that he will not run in Indy.
Ohio State CB Chimdi Chekwa - Severely dislocated his right wrist in January's Sugar Bowl and required surgery. Also a track star at OSU, Chekwa should be able to run at the Combine.
Pittsburgh DE Greg Romeus - Tore his right ACL on November 11 after returning from September surgery to repair a disc in his back. Romeus may spend his first NFL season on injured reserve.
North Carolina FS Deunta Williams - Fractured his right fibula at the ankle joint in the Music City Bowl and had surgery on January 4. Williams is questionable to work out before the NFL draft.
