Longhorns lose a WR, Tigers down a RB/KR

Coaches across the Big 12 are opening camp Thursday or hosting media days, and we've already seen news from a pair of them.

Texas coach Mack Brown announced receiver Malcolm Williams will miss his senior season and focus on a family situation, as well as academics.

The pair met on Thursday morning and made the decision, Brown said.

"He’s had some tough things happen that would be tough for all of us, that got tougher in the summer," Brown told reporters. "He was planning on playing, but some more things popped up. This morning, we talked. I want what’s best for him. I wish him well.”

Williams, a 6-foot-3, 220-pounder who caught 24 passes for 334 yards and two scores last season, would have been the team's lone senior receiver. He was also the team's second-leading receiver 2009 behind Jordan Shipley, when he caught 39 passes for 550 yards and two touchdowns.

Missouri also shared some bad news as camp opened. The Tigers had four featured running backs last season, but may have to make do with three this season, according to multiple reporters on the scene in Columbia for the first practice of fall camp.

Marcus Murphy had surgery to repair a torn labrum in his shoulder and his return is indefinite after rushing 22 times for 181 yards and two touchdowns as a freshman in 2010.

Murphy was also the team's top kick returner, averaging just fewer than 20 yards on his 24 returns
