Alexander's latest knee complications could put his ability to play the 2014 season in jeopardy and is likely to hit free agency next month. Given his struggles to stay healthy throughout his career, potential suitors including the Chargers, may shy away from Alexander.
Alexander is only 25 years old but has already undergone five previous surgeries in his left knee dating back prior to when he entered the NFL as an undrafted free agent with the St. Louis Rams in 2010.
Before originally suffering a torn right ACL in training camp last August, Alexander emerged as quarterback Philip Rivers' number one receiver down the stretch in 2012, catching 37 passes for 658 yards and seven touchdowns. It was the longest stretch Alexander was able to stay healthy and productive in his NFL career.
