Los Angeles Rams defensive end Myles Garrett will undergo arthroscopic knee surgery and be placed on injured reserve, sidelining him for at least the next four games.

Garrett will be eligible to return to the Rams' roster in Week 6.

Pro Football Doc on Myles Garrett's Knee Surgery

Pro Football Doc said Garrett's recovery timeline will depend on what is found and addressed during the arthroscopic procedure.

If Garrett undergoes a meniscus trim, Pro Football Doc expects him to have a chance to return after his four-game IR stint. If the procedure requires a meniscus repair, however, Garrett would be sidelined significantly longer.
