Former Nevada quarterback Carson Strong is arguably the most intriguing quarterback in the draft from a health standpoint.The 22-year-old has had three surgeries on his right knee, including two last year.During the first surgery in 2017, he had eight biodegradable screws inserted into his right knee to address osteochondritis dissecans, an issue caused by poor blood flow to part of the bone in the knee.With the poor blood flow, part of the bone “dies out” and the overlying cartilage wears out, much like an area of grass does if the underlying dirt is not watered, explained ProFootballDoc, Dr. David Chao.To remedy the issue, surgery is performed to repair and reestablish blood flow to the area.“This is something that is usually of long-term concern,” Chao said.The surgery kept him out his senior year of high school and he red-shirted during his first year at Nevada.In his sophomore year, Strong dealt with significant swelling and soreness in his right knee. Despite the knee issues, he won Mountain West Conference Offensive Player of the Year and finished the season with 2,858 passing yards, 27 touchdowns and 4 interceptions. However, he underwent another surgery on his ailing right knee in February last year.“The February surgery indicated that the original high school surgery did not fully work long term,” Chao said. “He required a graft, this time from his hip bone.”Strong was given a projected timeline of 6-to-12 months. In August last year, he underwent a scope to address scar tissue in the knee, then was cleared for the start of the season.He reportedly dealt with swelling and inflammation throughout the season, but repeated as Mountain West Conference Offensive Player of the Year. Strong played all 12 regular season games and finished with 4,175 passing yards, 36 rushing yards and 8 interceptions.He chose to sit out of the Quick Lane Bowl against Western Michigan on Dec. 27 after consulting with the Los Angeles Rams’ team doctor about his right knee.The hope is the extra time to let his knee heal will allow him to look good and pass the required physical at the NFL Draft Combine. Strong has all the arm talent and pocket presence to be an NFL quarterback, but the ProFootballDocs believe that his long-term knee issues will cost him some draft position.Injury history data provided by the 2022 rookie injury guide written by Dr. Ethan Turner, PT, DPT.
