Arizona State was without No. 1 running back Cameron Marshall Thursday at the Dickey Dome.
Marshall, coach Dennis Erickson said, has a sore ankle but is expected to practice Friday. James Morrison, a junior, stepped in with the first team Thursday.
Coyle, a special teams player last season, will back up Gerell Robinson as a slot receiver, Erickson said, and will play in the two-tight end set.
"He's going to play," Erickson said of Coyle. "With the offense we run, everything's going real fast, we've got to make sure we've got guys who can go in and out and he's really improved."
WR Mike Willie made a great adjustment on a pass from Brock Osweiler when the first teams on offense and defense faced each other in team drills. Willie fought off physical coverage from CB Osahon Irabor, then turned to bring in a deep ball from Osweiler.
