Denver Broncos running back C.J. Anderson underwent an MRI on his right knee Wednesday night that revealed he did not tear his ACL, a source told ESPN's Adam Schefter.
Anderson is having more tests on Thursday, a source told ESPN's Josina Anderson.
Anderson missed practice Wednesday to have the knee examined. His right knee buckled slightly during an 11-yard run on the last play of the first quarter of the Broncos' 27-9 victory over the Houston Texans on Monday night.
