Injuries continue to mount for the Dallas Cowboys through the first quarter of the season. Center Joe Looney is now set to miss up to three weeks after suffering a MCL Sprain on the Cowboys’ first drive against the Cleveland Browns Sunday.

In case the sizeable injury list has become overwhelming, here is a list of the Cowboys injuries and possible replacements.

Joe Looney, C (2-3 weeks)

Replacement: Tyler Biadasz

Rookie Tyler Biadasz is expected to make a first career NFL start for this coming Sunday’s game against the New York Giants. The Cowboys (1-3) host the Giants (0-4) at 4:25 p.m. ET from AT&T Stadium in Arlington, Texas.

La’el Collins, RT (out for season)

Replacement: Brandon Knight

Right tackle La’el Collins will miss the rest of the season after he undergoes hip surgery that is scheduled for Wednesday. Collins opened the season on injured reserve and could have returned to action against the Browns, but coach Mike McCarthy said Collins was a “ways off.”

Undrafted rookie Terence Steele has started the first three games at right tackle, beating out veteran Cameron Erving for the spot. Erving suffered a knee injury in the season opener and is on injured reserve.

Steele struggled Sunday against Myles Garrett – giving up two early sacks before being replaced by Brandon Knight.

Chidobe Awuzie, CB (Returns week 6)

Replacement: Trevon Diggs

The Cowboys lost Chidobe Awuzie because of a hamstring injury suffered in week two against the Atlanta Falcons. Stepping in during his abscene has been rookie corner Trevon Diggs. Diggs is going through the growing pains expected as a rookie, but has shown an ability to excel at a position that is all about confidence and technique.

Anthony Brown, CB (Returns Sunday)

The Cowboys opted to release veteran defensive back Brandon Carr Tuesday afternoon, which signals Brown is ready to return from a rib injury that popped up on the injury report following their week on game against the Los Angeles Rams.

Sean Lee, LB (Returns week 7)

Replacement: Aldon Smith

Veteran Linebacker Sean Lee began the season on injured reserve after being held out for the back half of training camp. Dallas has moved towards more of a 3-4 base because of their lack of linebacker depth, which has seen Aldon Smith fill in as one of the outside linebackers.

Leighton Vander Esch, LB (Returns week 7)

Replacement: Joe Thomas

Middle linebacker Leighton Vander Esch underwent surgary on his broken collarbone following their week one loss against the Rams. Vander Esch missed the last seven games of the 2019 season with a neck injury that eventually required a minimally invasive procedure in the offseason to fix.

Fortunately, this new injury is a bone injury that can be fully recovered once it is healed.
