Cowboys rookie left guard Connor Williams will have arthroscopic knee surgery Wednesday afternoon, coach Jason Garrett said.

Garrett anticipates Williams’ absence being a “short-term thing rather than a long-term thing” with Williams’ return expected sometime this month.

The Cowboys will have to find a replacement for at least this week’s game against the Eagles, and backups Xavier Su'a-Filo and Adam Redmond will compete for the job.

Joe Looney, who has spent the season starting for Travis Frederick at center, also is a possibility to move to left guard. That would put Redmond at center.

Right tackle La'el Collins, who previously played left guard, will remain at his current position.

“We’ll just have a little competition for that spot,” Garrett said. “We have some guys we have on our roster who we like, Xavier Su’a-Filo, Adam Redmond, those guys will get opportunities there, and we’ll see how it plays out through the course of this week at practice.

“All options are available to us.”
