Tight end Zach Ertz will ''most likely be sidelined for at least two weeks'' for No. 4 Stanford with a lower right leg injury, leaving one of the team's most productive units shorthanded.
The school announced Monday that Ertz is expected to miss Saturday's game at Oregon State and the Nov. 12 matchup against sixth-ranked Oregon that could determine the Pac-12 North champion. However, he has not been completely ruled out next week when the Ducks visit Stanford Stadium.
Ertz appeared to injure his right knee on the opening kickoff of Stanford's 56-48 triple-overtime victory at Southern California on Saturday night. He has 22 catches for 308 yards and three touchdowns this season.
Kicker Jordan Williamson and offensive tackle Cameron Fleming are day to day. Their injuries were not disclosed.
