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 is likely to lead the underdog Trojans against the defending Pac-12 champion Huskies (3-1, 0-1). Offensive coordinator Graham Harrell is working overtime to train his third starting quarterback in five games — and the non-quarterbacks who would be Fink's backup, including a walk-on safety and a starting receiver.
