A rough practice Wednesday was felt Thursday, as neither tailback Devin Rushing and receiver Jalen Robinette participated.
Both are probable starters.
Coach Troy Calhoun didn't specify the injuries beyond saying Rushing (who was wearing a boot on his right foot) had "an ankle," and Robinette "had a leg."
"I do think both of them are going to be OK," Calhoun said. "Whether it's four days or eight days, we'll just see."
The Falcons practiced in full pads on Tuesday and Wednesday, with Wednesday's session including a version of Oklahoma drill - something the Falcons hadn't run in years.
"We are building guys that down the road are going to have to kill an enemy," coach Troy Calhoun said. "So you better have combative, physical practices."
Pearson doesn't practice
Quarterback Kale Pearson was dressed for practice but didn't participate in any team plays after completing his mile-and-a-half aerobic fitness test on Thursday morning.
Pearson had to take the test now because a knee injury prevented him from taking it with the rest of the cadets this past spring.
Depth chart moves
With Rushing and Robinette out, freshmen RB Benton Washington and WR Cody Bronkar saw varsity time on Thursday.
Calhoun opted not to comment on either player.
The coach did single out was outside linebacker Jacob Onyechi, who is the No. 2 behind Dexter Walker.
"He's made a good leap," Calhoun said of Onyechi. "That's one of those where he's gaining some ground."
