FAYETTEVILLE -- University of Arkansas starting linebacker Bumper Pool watched the second half of the Razorbacks' 55-34 victory over Colorado State on Saturday from the sideline with his left arm in a sling.
Arkansas Coach Chad Morris said he didn't know the extent of Pool's injury, but he thinks Pool hurt his shoulder.
"We'll look at that tonight, tomorrow, and we'll see on that," Morris said.
Pool, a sophomore, came into the game as the Razorbacks' leader with 15 tackles. He had four stops against the Rams before being injured in the second quarter.
Hayden Henry, Grant Morgan and D'Vone McClure worked at linebacker in Pool's absence alongside senior De'Jon Harris.
