The San Francisco 49ers were dealt a blow in their bid to upset the Dallas Cowboys on Sunday when star defensive end Nick Bosa was declared out for the second half after suffering a concussion late in the first half.
Bosa was trying to get to quarterback Dak Prescott when he was held by La'el Collins. As Bosa was falling, his head hit the hip of a teammate. Bosa walked off the field under his own power but couldn't pass concussion protocol before the second half.
In the first half, Bosa had three tackles and a half-sack, helping San Francisco mount a consistent pass rush. Prescott absorbed three sacks.
At the time of the injury, the 49ers led 16-7, and they boosted the lead to 16 points later in the stanza.
Bosa had 15.5 sacks in the regular season, which ranked fourth in the NFL.
