TCU Horned Frogs running back Matthew Tucker's status has been upgraded to probable for Saturday's game against Iowa State, according to head coach Gary Patterson (via Stefan Stevenson of the Fort Worth Star-Telegram). Tucker injured his ankle in the Horned Frogs' 24-16 win at SMU.

The No. 15 Frogs' depth at tailback has been challenged over the last few weeks, as they lost Waymon James to a season-ending injury in their win over Kansas on Sept. 15. On Tuesday, Patterson toyed with the idea of having backup quarterback Trevone Boykin serve as the team's starting running back. That could still be an option, as Tucker's odds of playing are still only at "75-80 percent," per Stevenson.

Tucker has racked up 208 rushing yards on 52 carries, finding the end zone once. James was much more efficient prior to his injury, averaging 9.9 yards per carry in the season's first two games. For what it's worth, Boykin has certainly shown an ability to run, carrying the ball 12 times for 122 yards and a touchdown.
