Ex-Arizona Wildcat WR Poindexter likely tears ACL

The rookie has been in camp with the 49ers

Shawn Poindexter has been one of 12 former Arizona Wildcats in NFL camps, but his season appears to be over.

The rookie suffered a right knee injury while covering a punt in the second half of Monday's preseason game, and coach Kyle Shanahan told reporters Tuesday that the team fears Poindexter has a torn ACL. An MRI exam was expected to determine the extent of the injury.

"Poindexter still has to get his X-rays and everything," Shanahan said. "We were expecting the worst with the ACL, but we haven't got it confirmed yet."

As an undrafted free agent, Poindexter was a long shot to make the 49ers roster, but he might have able to land a spot on the practice squad because he has one thing you can't teach -- he's 6-foot-5 -- and he has upside as a late bloomer in football who emerged in his senior season with the Wildcats.
