Los Angeles Rams star Myles Garrett is expected to miss at least four games because of a knee injury that requires arthroscopic surgery, according to a person with knowledge of the edge rusher’s status. The person, speaking to The Associated Press on condition of anonymity, says the Rams will place Garrett on injured reserve. The two-time AP NFL Defensive Player of the Year was ineffective in the Rams’ 27-7 loss to San Francisco in Australia on Thursday night. Garrett will be eligible to return in Week 6.
