Lions' running back Jerome Harrison underwent brain tumor surgery on Friday to attack what was found during a physical with the Eagles after being traded, a trade that very well could've saved his life.
According to ESPN's sources, the surgery went well:
Jerome Harrison's surgery Friday to remove a brain tumor went well and doctors believe they removed all of the tumor, a source told ESPN senior NFL analyst Chris Mortensen.
A condition known as arteriovenous malformation, which is an abnormal connection between veins and arteries that often goes undetected, may have been a contributing factor to the tumor.
Harrison had complained of headaches in the past, but not enough to indicate that something was seriously wrong. Who knows when he finally would've said enough was enough to have a test done and discover the tumor without the trade.
Harrison was placed on the IR and will not play again this season, but he is expected to make a full recovery and possibly play again.
