After landing hard on his head and suffering a concussion, CeeDee Lamb had "a good day" on Friday back in Frisco.

Dallas Cowboys receiver CeeDee Lamb sustained a concussion against the Detroit Lions on Thursday night and was ruled out for the rest of the game.

Lions safety Brian Branch reportedly suffered an Achilles injury during Thursday night's victory over the Dallas Cowboys.

DETROIT — No one would argue that the Cowboys’ defense today isn’t substantially better than the unit that took the field at Denver in November. That didn’t keep the Cowboys from surrendering 44 points once again, allowing the Detroit Lions to take charge early in a 44-30 win for the home team that can only be considered costly for Dallas.

Week 14 gave the Cowboys a chance to prove they were playoff worthy, but they wilted in every big moment in the loss to the Lions.

The Dallas Cowboys won the toss and deferred, giving the ball first to Detroit. The Lions offense got off to an explosive start thanks to Jahmyr Gibbs, who turned a lateral and a catch into gains of 19 and 26 yards.

The Dallas Cowboys had all the momentum heading into Week 14, but a brutal loss to the Detroit Lions severely hurt their playoff chances.
