There is one upgrade among the five Arizona Wildcats players who were listed as questionable last week but not did not play.
Slot receiver Johnny Jackson (ankle) is considered probable on the team’s weekly injury report, issued Thursday afternoon. Jackson injured the ankle at Stanford, when he caught 10 passes — nine in the second quarter.
Garic Wharton filled in last week at the position and made the most of his first expanded playing time.
Defensive lineman Willie Mobley (ankle) also is listed as probable.
The four still questionable are:
–Starting offensive guard Trace Biskin (toe). He has missed the past three games, with Shane Zink starting in his place.
–Starting safety Jared Tevis (ankle). He suffered the injury Sept. 29 against Oregon State and has missed the past two games. Tevis went through some warm-up drills last week but not make it into the game. Redshirt freshman Patrick Onwuasor has started at the “Bandit” safety for Tevis.
–Defensive end Kirifi Taula (shoulder). The sophomore suffered the injury two games ago at Stanford.
–Starting center Kyle Quinn (ankle). He has missed two games, with senior Addison Bachman filling in.
Two players have been ruled out: Wide receiver Terrence Miller (ankle) and defensive lineman Dominique Austin, who will miss the rest of the season, coach Rich Rodriguez said Monday.
