FRISCO, Texas -- The shuffle on the Dallas Cowboys' offensive line will continue.
Center Joe Looney suffered a sprained medial collateral ligament in his right knee on the first play of Sunday's loss to the Cleveland Browns and could miss two to three weeks, a source told ESPN.
Rookie Tyler Biadasz will take over for Looney with left guard Connor Williams working as the backup center.
The Cowboys have been without right tackle La'el Collins since the season began, and he is scheduled to undergo hip surgery on Wednesday that will require a six-month rehab, multiple sources told ESPN. Left tackle Tyron Smith missed two games with a neck injury, but he returned against the Browns and did not appear to suffer any setbacks.
Undrafted rookie Terence Steele replaced Collins in the starting lineup, but he was pulled in favor of Brandon Knight after giving up two sacks to Myles Garrett.
Biadasz has played 133 snaps in the past two games in taking over for Looney, who suffered an ankle injury in the Week 3 loss to the Seattle Seahawks.
Tight end Dalton Schultz suffered a bruised thigh late in Sunday's loss to Cleveland, but the expectation is he will be able to play this week against the New York Giants.
The Cowboys continued to make roster tweaks Tuesday, releasing backup defensive back Brandon Carr and offensive tackle Alex Light.
The club also signed offensive tackle Greg Senat to the active roster off the Browns' practice squad and added offensive tackle William Sweet to the practice squad.
Carr, a 12-year veteran, was signed to the practice squad after final cuts and later signed to the active roster, but he only played 21 snaps in the first four games despite the Cowboys' injuries in the secondary.
