The hit occurred in the first quarter, and Pierce left the field shortly thereafter. According to ESPN's Adam Schefter, Pierce underwent testing to determine if he had sustained a concussion. If it turns out Pierce does have a concussion, he won't be able to return to action until going through the NFL's concussion protocol.
Pierce is expected to start the first two games of the season for Baltimore while Ray Rice serves his two-game suspension for the offseason domestic violence incident involving his now-wife. The 24-year-old Pierce had 436 rushing yards and averaged 2.9 yards per carry last season, his second in the NFL.
Pierce underwent shoulder surgery in January and had been practicing without limitations during training camp. In his absence Saturday, the Ravens gave increased carries to Justin Forsett and Lorenzo Taliaferro.
Baltimore opens the 2014 season Sept. 7 against the Cincinnati Bengals.
