Texas Tech wide-out Robert Johnson and linebacker Fletcher Session are not expected to participate in Saturday`s game against Colorado. Texas Tech tells us that both Johnson and Session did attend practice today. Both have been left off the dress roster for this Saturday`s game. Session separted his shoulder September 16th against TCU, and it`s unknown if his injuries are a contributing factor to his expected absense. An internet fan website reports that Johnson has been suspened due to a violation of team rules. We talked to a Texas Tech official, and he could not give our station a reason why the two players have been left off the Colorado dress roster.
