Stanford running back EJ Smith will miss the rest of the season due to an undisclosed injury, coach David Shaw announced at his press conference on Tuesday.

Smith did not play this past weekend against Washington after picking up an injury against USC on Sept. 10. Initial thinking was that Smith would only be sidelined for a short period of time, but further evaluation this week changed things.

“I don’t think there’s an option for him to continue,” Shaw said Tuesday. He’s got to get his body taken care of. Trust me, he wishes it was not this way. He told me last week, ‘Coach, I can’t wait to play against Oregon. I’m going to be there for you. I need to get back in there.’ But the doctors are right and it’s wise for him — both now and for his future — to get this taken care of and come back in ’23 bigger, faster, stronger.”

The son of legendary NFL back Emmitt Smith, EJ Smith had 206 yards and three touchdowns in his first two games this season. He opened the year with 118 yards on 11 carries against Colgate, taking the opening play from scrimmage 87 yards for a touchdown. Smith is in his fourth year with Stanford.

“I know it’s really disappointing for him, disappointing for the whole team,” Shaw said. “I think he’s a special young man and a special football player. Was just really coming into his own. Future’s bright.”

Casey Filkins is expected to start in Smith’s absence. He ran for 100 yards on 20 carries against Washington over the weekend.

Elsewhere on the injury front, tackles Walter Rouse and Myles Hinton and fullback Jay Symonds were all labeled as “questionable,” per Shaw. He said none of the three participated in practice on Monday. They’ll make an announcement later in the week one way or another.

Stanford (1-2, 0-2 Pac-12) faces No. 13 Oregon (3-1, 1-0 Pac-12) in Eugene on Saturday at 8 p.m. PT on FS1.
