Starting Lions' left tackle Jeff Backus may have given Lions' CEO Matt Millen the biggest scare of his current term as team president.
Backus, who went down with what seemed to be an awful knee injury early during Tuesday's practice, received good results after Lions' trainer's examined his left knee.
"It looked a lot worse hopefully than it was,'' Millen told the Associated Press. ``The trainers worked on him right away and got a feel for him. The initial signs were positive. The knee was real tight, and that was good."
The test did show that Backus may have suffered a deep bruise after twisting his knee.
Backus will have another MRI Tuesday evening, and team trainer's will keep a careful eye on how Backus' proceeds through the remainder of camp.
Pending the second MRI result, Lions' officials had not decided whether or not Backus would miss any more practice sessions.
