=== USC QB Barkley exits with injury ===
 
 Pasadena,  CA  (Sports Network)  - USC  lost its rivalry  game against UCLA on
 Saturday and may have lost its starting quarterback as well.
 
 Matt  Barkley, USC's golden-armed QB, was hit hard by UCLA's Anthony Barr late
 in  the fourth quarter and walked to the sideline holding his shoulder. He did
 not  return  the next series, and  Los Angeles Times writer Scott Wolf tweeted
 the senior may have a separated shoulder.
 
 Barkley completed 20-of-38 passes for 301 yards and three touchdowns but threw
 two  interceptions in the 38-28 loss, the fourth of the year for the preseason
 No. 1.
 
 The  Trojans, who can  not play for the Pac-12 title, host their final game of
 the  season  next  Saturday  against  Notre Dame,  the  only  undefeated  team
 remaining eligible to play for a national championship.
