Oakland Raiders wide receiver Michael Crabtree was ruled out for the remainder of Saturday's Wild Card Game against the Houston Texans in the fourth quarter as trainers continued to evaluate him for a concussion, according to ESPN's Adam Schefter.
Crabtree has dealt with an ankle injury at various times this season, but it hadn't forced him off the field. In fact, the receiver hasn't missed a game since 2013 while a member of the San Francisco 49ers.
While the 2009 first-round pick had a few solid seasons with the 49ers, he has been even better since joining the Raiders in 2015.
