Fifth-year senior running back Jason Evans and junior offensive tackle Allen Smith will be out for the remainder of the 2007 season as a result of injuries, head coach Jim Harbaugh announced on Tuesday.

Evans tore his left ACL during Stanford’s 21-20 victory at Arizona on Oct. 20 and is expected to have surgery next week. The game was Evans’ first collegiate start, and prior to the injury he rushed for a career-high 78 yards on a team season-high 21 carries. He also scored his first touchdown of the season and the second of his career on a two-yard run with 0:05 remaining in the first half.

Evans finished his 2007 season with 30 carries for 105 yards and a touchdown to go along with five catches for 51 yards. He also had two kick returns for 51 yards. He played in each of the team’s first seven games and also contributed three tackles on special teams.

“I’m still looking forward to a lot of good times for this team this season,” Evans told GoStanford.com. “Somebody will step in and do well. That’s what everybody has done so far. I still think we can reach our goal to make a bowl game.”

Smith injured his left knee in Stanford’s third game of the 2007 season versus Oregon on Sept. 22 and had surgery the following week. He has not played since, snapping a string of 23 consecutive games started.

“While I’m disappointed to lose my season because I think I could have contributed more to our goals, I am so proud of the guys that have stepped up and helped replace some of the veterans on this team that have been injured,” Smith said to GoStanford.com. “My rehab from this injury will take care of itself and there’s still a lot more football for me to play in the future, but this team will continue to strive towards its goals.”

The two injuries highlighted a trend for 3-4 Stanford this year. The Cardinal was without the services of its top two tailbacks last week, sophomore Toby Gerhart and junior Anthony Kimble. Starting sophomore tight end Jim Dray had his season cut short with a knee injury, while former starting senior quarterback T.C. Ostrander was sidelined after suffering a seizure in the last week of September.
