Observations from warmups before the Arizona Wildcats’ game against Utah at Arizona Stadium tonight (7:30 p.m., FS1):
* Tight end Trevor Wood, who has missed the past two games because of an ankle injury, participated in warmups and is expected to play. Wood is listed atop the flip-chart depth chart, but freshman Bryce Wolma lined up with the first unit during the “team” portion of warmups.
* Like Wood, defensive tackle Parker Zellers was listed as questionable because of an ankle injury. But Zellers is dressed, and it appears he will return after missing last week's game at UTEP.
