LOS ANGELES (AP) - Quarterback Kedon Slovis is in the concussion protocol for No. 21 Southern California, increasing the likelihood of Matt Fink making his first career start at No. 17 Washington this weekend.

    

Coach Clay Helton confirmed Tuesday night that Slovis isn't currently cleared to practice or play.

    

Slovis was injured on the second play of the Trojans' victory over then-No. 10 Utah last Friday. Fink stepped in and passed for 351 yards with ample help from his outstanding receivers in USC's 30-23 win.

    

Fink would be the third starting quarterback in five games for the Trojans (3-1, 2-0 Pac-12). J.T. Daniels was lost to a season-ending knee injury right before halftime in USC's season opener last month, and 18-year-old freshman Slovis stepped in.
