The Dallas Cowboys are looking to extend their win streak to four games in Week 14, but they will have to finish out this Thursday night showdown with the Detroit Lions without one of their star wideouts. 

In the third quarter, CeeDee Lamb was injured while attempting to catch a touchdown. He hit his head on the turf, and the Cowboys’ medical staff quickly ruled him out with a concussion, per the Amazon broadcast.

Check out what happened, here:

Lamb was in the midst of another massive performance, as he caught six passes for 123 yards before exiting the contest. The four-time Pro Bowl receiver had caught 51 passes for 744 yards and three touchdowns in nine games played entering this week.

This unfortunate development opens the door for George Pickens, who entered this week ranked No. 2 in receiving yards with 1,142. The former Pittsburgh Steeler and Lamb are the only duo in Cowboys history to average 80 receiving yards per game in a season. Naturally, Detroit’s defense turned its focus to Pickens when Lamb exited, which gave Ryan Flournoy some opportunities to make plays. In the fourth quarter, he caught a 42-yard touchdown pass to pull Dallas within three points. 

If there’s a silver lining with the Lamb injury, it’s that he’s going to have more time to heal with Dallas on a mini bye. Up next for the Cowboys are the Minnesota Vikings on Dec. 14.
