New England Patriots tight end Rob Gronkowski will not play again this season after MRI scans confirmed he suffered a double ACL and MCL injury in Sunday's 27-26 victory over the Cleveland Browns at the Gillette Stadium, reports NFL.com.
The 24-year-old is now facing up to a year on the sidelines, with the anterior cruciate ligament and medial collateral ligament tears, and will be immediately placed on season-ending injured reserve.
Gronk only returned to NFL action in Week 7 after missing the first six weeks of the 2013 season as he continued his rehabilitation from multiple back and forearm surgeries during the off-season.
Head coach Bill Belichick has now been denied the services of one of the Patriots' key offensive players, who will now face a race against time to be fit for the start of the 2014 campaign.
The injury Gronkowski suffered occurred following a collision with Browns safety TJ Ward, who went low to stop him on a 21-yard reception from quarterback Tom Brady in the third quarter.
After several minutes of treatment on the ground, the Patriots star was eventually carted off the field on the back of a truck.
