Las Vegas Raiders star defensive end Maxx Crosby is expected to undergo season-ending arthroscopic ankle surgery, according to ESPN's Adam Schefter.
Crosby later confirmed the news on Instagram (h/t NFL Network's Ian Rapoport):
Crosby has been hampered by ankle issues throughout the year, causing him to miss a Week 4 matchup with the Cleveland Browns. He initially suffered the left high-ankle sprain near the end of a Week 2 win over the Baltimore Ravens.
The three-time Pro Bowl pass-rusher was already ruled out of Las Vegas' clash with the Atlanta Falcons on Monday prior to the surgery announcement.
